Could you provide me with your steps to reproduce, so I can try to find out 
what's wrong?

One possibly important thing: the code that finds what sys.path entry 
contains the egg is currently case-sensitive and separator-sensitive.  It's 
possible that if your PYTHONPATH uses lowercase and slash separators and 
the egg is the other way around, or vice versa, the container checking may 
be failing.  You can verify this by printing sys.path after the require() 
and see if the paths are the same.
