Are you sure you need to find python 2.49? It sounds like you need blender 2.49, with correctly installed python. I am using blender 2.49 with python 2.6 and I can export dae. Can you provide me some info about your system? Do it like this, go to help,-> system information. Then change to text view. Open system-info (or something like that) and post contents here, so I may be help you.
