I believe this is a known issue and appeared last Fall in Natty. I think it's caused by a combination of the /usr/athena symlink and some stupidity in how Python tries to determine where its installed. The official answer is probably "/usr/athena/bin" is now deprecated and users should switch their scripts to use /usr/bin. I _think_ a shebang line of "#!/usr/bin/env python" will work and will prefer /usr/athena/bin on older machines if they still want Solaris compatibility, but non-Debathena platforms have been dead for some time now.
Someone who remembers more about this should chime in...
