/usr/local/lib/pythonX.Y/site-packages is the standard site dir for a python
installation done in /usr/local (without options). Debian does include
/usr/local/lib/pythonX.Y/site-packages in sys.path as well. Many (upstream)
developers complain that two python installation should not get into it's way.
Therefore having two differently named site dirs in /usr/local (if you do want
to have only one, symlink dist-packages to site-packages in /usr/local).

The default install (sudo easy_install ...) now goes into
/usr/local/lib/pythonX.Y/dist-packages, and doesn't do anything anymore in
/usr/lib, overwriting the distribution files. If you do want to install for a
Debian package, you need to call --install --install-layout=deb or move the
files from <tempdir>//usr/local/lib/pythonX.Y/dist-packages into the final
location yourself.
