also:

     - easy-install.pth; When you install two different packages  
under GNU stow, then stow can install both of those packages (by  
creating symlinks pointing to each file from each package) *unless*  
both packages created a file in the same location.  Two different  
Python packages both installed by setuptools (without --single- 
version-externally-managed) will create a file in the same location  
-- the easy-install.pth file.  If setuptools didn't need to create  
this file (and if it accepted installation into a directory not  
currently on the PYTHONPATH, per http://bugs.python.org/setuptools/ 
issue54 (be more like distutils with regard to --prefix=)), then it  
would be GNU stow-compatible.
