This list is for beginners trying to learning Python the language, not
trying to solve arbitrary Python-related problems. You are more likely
to get an answer by asking on one of the larger/busier lists, like
python-list at python.org (also available on Usenet under
comp.lang.python). You are more likely to find somebody who uses
easy_install and a Mac there.
But in the meantime, my *wild guess* is that this is a file association
problem. If you call the python app directly with "python", the most
recently added version (version 2.6) gets called, but if you try to run
the easy_install directly script, the Mac automatically associates it
with Python 2.5 and installation fails.
Can you show us exactly how you are calling the easy install script?
Another possibility is that it is an issue with the PATH. If you are
calling "python" from the command line as a regular user, it might be
picking up one version of Python, but if you call it as root
(superuser), you might get a different PATH and therefore a different
version of Python. Again, this depends on how you are calling the easy
(I emphasis that these are guesses... I haven't used Apple Macs
regularly since System 7, back when Steve Jobs was still persona non
grata at Apple. How times have changed.)
