For me it seems like that you have multiple Python instances  
installed. One of them most likely originates from fink and it is  
somewhere in /sw (the executable should be in /sw/bin). Another one  
(the one shipped by Apple) resides in /usr/bin/python which is a  
symbolic link to /System/Library/Frameworks/Python.framework/Versions/ 
2.5/bin/python. Maybe these multiple instances were the cause for your  
problems: you usually use the one from /sw/bin, but after installing  
XCode, the Python installation shipped by Apple took precedence. After  
reinstalling Python, you got back to the one in /sw/bin again. Or  
maybe not, I'm just guessing :)
