I maintain PyInstaller. Personally, I can't do anything to fix this, if 
objcreator.py insists on unconditionally calling os.listdir(). I suggest two 
solutions:

1) Modify objcreator.py to use the not-standard-but-almost-and-widely-used 
pkg_resources API. PyInstaller does not support this yet, but pkg_resources is 
  already very extensible, and PyInstaller (at runtime) could register a hook 
to let it find resource files in any way they're packaged (eg. PyInstaller 
even supports encryption...).

2) The same as above, but rolling up your own API instead of relying on 
pkg_resources.

#1 looks like the best option of course, since I don't like having to reinvent 
the wheel. It also means that PyInstaller, py2exe and others just have to 
support pkg_resources.
