Where is a module usually installed?

[Peng Yu]

My Python is installed in the following location.
~/utility/linux/opt/Python-2.6.5/

I then installed SCons (http://www.scons.org/) using the command
"python setup.py install", which install it at
~/utility/linux/opt/Python-2.6.5/lib/scons-2.0.0.final.0

sys.path doesn't have the above directory. I have to add it to my PYTHONPATH.

Would a python module usually be installed at the following location?
~/utility/linux/opt/Python-2.6.5/lib/python2.6
