changing sys.path

[Andrea Crotti]

I think I finally located the issue with the sys.path extension.

The problem is that I have many namespace directories, for example

lib:
  - sub1
  - sub2

lib:
   - sub3
   - sub4

But to have everything working I had lib.sub3 in easy-install.pth.
Now if I try to add something else to the path it doesn't take care of 
the namespace
declaration
(every __init__.py in the packages contains: 
__import__('pkg_resources').declare_namespace(__name__))
and just doesn't find the other submodules..

If I try to add manually lib.sub1, lib.sub2 changing the sys.path the 
imports will only work for the first one.

Strangely if I just create a dev_main.pth in site-packages containing 
the same paths, everything works perfectly.

Any suggestions now that the problem is more clear?
Thanks,
Andrea
