JM,

Thanks for the response, you're correct '' is pre-pended to the path
in interactive mode. I've tried adding . to my PYTHONPATH and it
doesn't solve the problem.

When imported from interactive python the paste.deploy module is located at:

>>> import paste.deploy
>>> paste.deploy.__path__
['/home/brian/webapps/test_dyn/lib/python2.7/paste/deploy']

My path for both interactive and non-interactive contains:

/home/brian/webapps/test_dyn/lib/python2.7

>From the interactive interpreter I can import paste if my working
directory is inside of the.

/home/brian/webapps/test_dyn

Moving to a working directory above "test_dyn" point causes the import
to fail in the interactive interpreter as well.

I am able to import packages located the lib/python2.7/site-packages
directory of my virtualenv instance, but not the lib/python2.7
directory.

Thanks again,
Brian
