Hello, could someone please help me understand a strange problem, possibly associated with PYTHONPATH. When I import matplotlib, pylab, or scipy from any directory other than the root installation directory, it fails. However, if I’m in the python installation directory there are no errors. Thanks in advance! Please see below:

You have a new.py module somewhere which is interfering with the standard library's "new" module. Find it and rename it.

Thank you!
I see this is a deprecated module, might I break something else?
Thanks again,

I wonder if I've misunderstood or made a mistake? I renamed a file:
/usr/lib/python2.5/new.py to /usr/lib/python2.5/new.bak
and everything worked... but now, after logging out and logging back in
again, I'm getting the problem again?
Perhaps that was the standard libraries module? But I cannot find any other
new.py files?
Thanks,
john

I'm revisiting this with a new round of errors. I keep getting this error,
maybe related as before to the 'new' module, but I cannot tell?? Does anyone
know what is going on?

/usr/lib/python2.5/new.py is the standard library's module. Leave it alone. If you are still having problems and cannot find another new.py module anywhere, edit pkg_resources.py to print out new.__file__ just before where the exception occurs.

Thanks.
I haven't done this yet, but I think the problem may have been related to my
locales setting. Presently all is working after editing /etc/sysconfig/i18n
to update LC_CTYPE and other variables.
