So I need to defragment the hard drive of my mac book so that boot camp will let me repartition it. I would like to avoid having to clone the drive and then clone it back. What are some good utilities for defragmenting (or any other tools that will help with the repartitioning problem).

All the defrag programs look good, but I wasn't wanting to pay anything for this, and I didn't have a external drive I could back up to. So what I did instead was to zip up all the data files I had on the laptop (ie everything other than programs) then I copied them to a desktop. This took me from about 35GB free to over 90GB free space on the drive.
The boot camp utility was then able to properly format the 15GB partition I wanted. And then I copied everything back. I'm not entirely sure how boot camp partitions drives, whether it is in contiguous blocks or not, so this may work all the time, or perhaps not.

matthewfrey is correct - you cannot repartition free space if it is not a contiguous block. iDefrag is a good choice, Drive Genius is another option. Using Carbon Copy Cloner or SuperDuper to clone the drive out and back is actually the best choice - faster, more efficient, and free. (plus you have a bootable backup, just in case)
asle is also correct in that OS X does not require forced defragmentation of the primary drive under normal operation (unlike Windows). OS X maintains proper fragmentation levels on the boot volume all on its own. In fact, you can make your system run SLOWER by defragging the boot volume!
Repartitioning a drive for Boot Camp is NOT a normal operation, however.
Defragmentation is widely recommended for external volumes used for video data storage - you want large continuous block of free space in order to prevent dropped frames.

The question is, does OS X need a defragmenter. Mac OS9 did. I would say it can help if you have many large files (video etc.) or you are running low on disk space. For a starter Cocktail does a good work at maintenance (http://www.maintain.se/cocktail/index.ph...) although ti does not do defrag. You would need something like iDefrag (http://www.coriolis-systems.com/iDefrag....). I have tried iDefrag with good experience. But did I notice anything else than prettier defragement graphic bars? Not really, or someone else may have different experience. Take a read here about defragement and OS X: http://reviews.cnet.com/8301-13727_7-103...

I ran into the same situation before myself - Bootcamp needs enough contiguous free space in order to partition the drive - I used idefrag, it worked well

I am using Fusion to run Windows as a virtual machine. This may be one option for you - instead of buying a defrag program, buy VMware fusion. you can download a trial version (30 days) that can get you up and running at no cost immediately. If you don't like it you can still go back to your original idea

If you want to defrag the drive and the cloning is not the thing that you want, then in that case you need to use any of the drive defrag software as it might be the case that defrag not let you defrag the files those are more than 20KB of size, while you are editing videos or images most of the file get a lot of space and these all files are out of Mac utility scope.

Defragmenting in Mac Lion is almost not required at all. But when we are working with large files like media files, we need to defrag mac files using some third party defragmenting software like Stellar drive defrag.

Although, defragmenting boot volume enhances the Mac speed. But it is recommended to backup important data before initiating this process. And CCC and Stellar Drive Clone software are good option for Mac drive cloning. There are many tools which can be tried as free demo version available online on their respective websites .

I used iDefrag, and it worked fine. It not only cleared space for Boot Camp, but significantly improved the performance of my old (2009) MacBook Pro.

First, before diving into list of programs, note, you should never use these programs on a Mac with an SSD. Otherwise, you can damage your disk and the system.
Apps for disk defrag:
- iDefrag is the most popular app. It costs $32 but provides a trial period.
- Drive Genius is a more powerful program, which allows you to perform a full range of preventive actions, work with HD partitions and restore the data. The price is $99.
- TechTool Pro 5 is a universal tool for Mac performance optimization, which has a defragmentation option as well. TechTool Pro 5 costs $ 98.
