"paster shell my.ini" fails when lib folder is present but base.py is missing

[deiferni]

recently we moved "ourproject.lib.base.py" to a sub-package inside the "ourproject.lib" package. This causes a "paster shell my.ini" to fail with:

Traceback (most recent call last):
File "/Users/deif/Library/VirtualEnv/sv11_py27/bin/paster", line 8, in

ImportError: No module named base

I think the bug lies in pylons.commands.is_minimal_template that checks the importerror against the string 'No module named lib.base' but should also check against 'No module named base'. the latter error is raised when the lib package exists but not the base module.
