... by administrators who want to add some local modifications, not by users who want to do some tests let me cite FHS: | The /usr/local hierarchy is for use by the system administrator when | installing software locally. It needs to be safe from being overwritten | when the system software is updated. It may be used for programs and | data that are shareable amongst a group of hosts, but not found in /usr. so, even if easy_install would install to /usr/local it still would be wrong. > Their Python interpreter has been modified to look both places.

The same cannot be > said for Pylons, SQLAlchemy, Setuptools, etc. again, please don't install them into global site-packages (no matter if you choose /usr or /usr/local). If you don't believe me it's a bad idea, just list eggs you installed on your system and I'll give you names of packages that you broke by using eggs.
