Uh, it was supposed to be a solution for you to add :-( It was an
explanation that you have a broken installation of Twisted.
First of all, Python works no unlike Java with regard to it's PYTHONPATH
environment variable. On my system I have installed Twisted into
~/opt/lib/python/ and have set PYTHONPATH to that same value.
Inside of ~/opt/lib/python/ I have
-rwxr-xr-x 1 mgeisler users 230K May 16 2007 gmpy.so
drwxr-xr-x 24 mgeisler users 4.0K Sep 16 2008 twisted
drwxr-xr-x 3 mgeisler users 4.0K Sep 16 2008 zope
among other files.
You can check that things are installed nicely by switching to some
other directory and starting the interactive python interpreter:
Python 2.4.3 (#1, Jun 11 2009, 14:09:58)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from twisted import version
Version('twisted', 2, 5, 0)
Likewise for GMPY:
>>> import gmpy
>>> x = gmpy.mpz(1234567891234567891234567)

That is fine, we have an old Redhat here with the same Python version.

It's not like it will mess things up to install Python, Twisted, and
GMPY globally. The packages will just sit nicely in the corner and
nobody will notice :-)
