I'm trying to build a package set for installing mwlib-0.12.12 on a Centos 5.4 
machine. The default python there is python 2.4, so I'm building a parallel set 
of RPMs using python-2.6 (which obviously install to a separate site-packages 
directory, so don't interact with the system ones).

Apart from a huge number of dependencies more than are listed on 
http://code.pediapress.com/wiki/wiki/mwlib-install, I've hit a problem. After 
building all the necessary dependencies I can compile mwlib correctly, but when 
I try to run mw-render I get the error message

$ mw-render 
Traceback (most recent call last):
  File "/usr/bin/mw-render", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 2562, in 
<module>
    working_set.require(__requires__)
  File "/usr/lib/python2.6/site-packages/pkg_resources..py", line 626, in 
require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 524, in resolve
    raise DistributionNotFound(req)  # XXX put more info here
pkg_resources.DistributionNotFound: twisted>=8.2

Which is wrong, because I have twisted-8.2.0 installed on the system. Any ideas 
where this error is coming from or what to do about it (I'm not a python 
programmer)? I must be close, but not there yet.
