You may be able to install Twisted (or even wsgilib) in your home
directory.  For example, the command:

    python setup.py --prefix ~/.local

will install Twisted (or maybe wsgilib) in ~/.local/lib/python2.4/site-
packages/.  Add that to your PYTHONPATH (eg in your .bashrc) and
you're basically all set.  Also, though Twisted has some extension
modules, they're optional.  So you should be fine without a compiler,
*except* that distutils doesn't cope so well with certain cases.  If
you find "setup.py install" fails for some reason, you can also just
add the unpacked source directory to PYTHONPATH and run it in-place
without installation.
