Good advice.  I second it.

I have python24, 25, 26, 27, and 32 installed with MacPorts, and
"python_select" (also from MacPorts) allows you to change the default python
version quickly and cleanly with a single command.  It's quite useful for
testing compatibility of scripts that use "#!/usr/bin/env python" as the
shebang line.  I haven't tried Fink, but the MacPorts approach works well
for me.

Good luck!
