After allowing the repaired solder joints to cool, test the port in question. If you're fortunate, it will function and you can clean the board and begin to reassemble. I used 93% isopropyl alcohol and an old toothbrush to clean any excess flux off.
Using an adhesive suitable for plastics, carefully apply the tiniest amount possible onto the "male" side of the seam. You will see a groove in the opposite side. Carefully press the halves together and clamp until the glue has set. Clean of any excess adhesive and enjoy!
