Hi Salim,

I can confirm this for Debian.
I've tried your script on Squeeze and it doesn't work.
The AccessGrid libs are installed in /usr/share/pyshared/AccessGrid3, 
get_python_lib() returns /usr/lib/python2.6/dist-packages.
I have 2 versions of python installed (2.5 and 2.6) and the package 
creates symlinks to the installed AG lib files in the lib trees of both 
python versions:
/usr/lib/pymodules/python2.5/AccessGrid3
/usr/lib/pymodules/python2.6/AccessGrid3

I searched for a way of figuring out where the libs are and the best I 
could come up with was to import the library and let python tell me its 
path:

import AccessGrid3
site_packages_dir = os.path.join(AccessGrid3.__path__[0], "AccessGrid")

In case of the "AccessGrid" package name the above would have to be (not 
tested):

import AccessGrid
site_packages_dir = AccessGrid3.__path__[0]

I wonder if this approach would work on all systems.

Regards,

Robert
