  1. I think i get one of these? This is what I’ve been getting:

    UserWarning: Module _mysql was already imported from /var/lib/python-support/python2\
    .5/_mysql.so, but /var/lib/python-support/python2.5 is being added to sys.path
    import pkg_resources

  2. Yes. Happens if you are playing with sys.path to inject another lib but there is an egg added later on. Especially for scripts very annoying.

  3. It is very annoying. I sidestepped the issue and tried the same using postgresql, and it went away. Weird thing is that for the wsgi bridge file I play with sys.path to import some modules, however I get this when I run the script that doesn’t append anything to the sys.path, so it must be happening someplace else.
