There's a special 'site.py' missing from this directory. You can fix
that by doing this:
cd /opt/tradelink/research/site-packages.beta
PYTHONPATH=. easy_install -d . SQLAlchemy-0.5.0rc3dev_r5205-py2.4.egg
My guess is that this directory was created by copying a
site-packages directory from somewhere, or by easy_installing to it
with the --site-dirs option. Either would have prevented
easy_install from creating the site.py that's necessary to make this work.
Without the special site.py, Python doesn't pick this directory up as
a "site" directory, and doesn't process PYTHONPATH eggs properly.
Note that you must use easy_install as described above to do this;
you can't just copy Python's site.py, as it's not the same file. The
one easy_install puts there forces .pth processing to occur on
PYTHONPATH, and then invokes the original Python site.py.
