I'm trying to change my PYTHONPATH. I've tried to change it in "My Computer" etc, but it doesn't exist there. I searched in the registry in some places, and even ran a whole search for the word 'PYTHONPATH', but to no avail.
However, it Python I can easily see it exists. So where is it?
MacOS 10.5.8, Python 2.6, Eclipse+Pydev 1.5.7

Python installation's site-package is, for example:
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages
create symlinks YOUR LIBRARY inside into site-package, for example:
cd /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages
ln -s /path/to/YOUR/LIBRARY/ YOUR_LIBRARY_NAME

Now You can use in commandline:  import YOUR_LIBRARY_NAME 
run Eclipse with Pydev, go to Preferences->Pydev->Interpreter Python
remove Your Python interpreter record, if exists;
click New and add Python 2.6 interpreter path, for example:
/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6

notice, that Eclipse Pydev display Python System Library, accept that
in  Library section click New Folder and write path to YOUR LIBRARY, for example:
/path/to/YOUR/LIBRARY/
click Apply - it is essential, because Eclipse Pydev built now his own "library map", when this operation finish - click [OK]
close Eclipse
run Eclipse again - now You should use in Pydev: import YOUR_LIBRARY_NAME
Can't find my PYTHONPATH
