AFAIK there are no symlinks at all created, everything resides
under /Library/Framework/Python.framework/Versions/2.6/bin.

A note to the OP: be cautious about replacing /usr/bin/python with your new
& shiny 2.6! That is likely to break the system, as OSX
uses /usr/bin/python and expects it to be the standard version shipped.

Creating 

/usr/bin/python2.6

should be safe though.
