OS X Skeletons Failed to Generate?

I have a brand new Macbook Air.  I installed PyCharm on it primarily for Django development.  Every time I use PyCharm to create a Python virtual environment, either via a 2.6 or 2.7 system interpreter, it generates the following:

Some skeletons failed to generate.  5 modules failed in 1 interpreter.

Python 2.7.5 (/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7)
Nav
_Qt
_Win
dl
imageop

Does anyone know if:

A) Is this something to worry about?
B) Is there a fix?
C) Am I doing something wrong?

Any help would be appreciated.

Tom
