So *something* is adding additional entries to sys.path in your Ubuntu
Python (but not mine).  If there's a way to make that happen, it could be
another solution.  I *don't* see any of that here (ubuntu 14.04, Python
2.7.6), even though there are multiple packages with egg files.

What does get_python_lib() show in this Python?

It did occur to me that finding an FHS-compliant directory that's already
in sys.path might be a solution, but when I discovered that, in all three
Linuces I have here, the intersection between the set of sys.path
directories and the set of FHS-compliant directories is empty, it seemed
pointless to suggest it.
