this is not an absolute path, why are we mangling the `sys.path` for this? this should be taken care of by the installer script.

If I run this in the same directory it returns empty (`''`). For an absolute path you would want something like this:

    import os
    this_dir = os.path.dirname(__file__)
    abspath = os.path.abspath(this_dir) 

But then again, I do not recommend mangling the `sys.path`
