On Debian-based systems, you should add these lines to ~/.pydistutils.cfg if you want to install eggs system-wide (substituting python2.4 if appropriate): [install] prefix=/usr/local [easy_install] site_dirs=/usr/local/lib/python2.3/site-packages This will ensure that easy_install does *not* try to overwrite system packages, although it may duplicate them in the interim. For more information, please see the "Custom Installation Locations" section of the EasyInstall wiki page, which describes other ways of customizing where and how packages are installed. This will of course duplicate system packages that do not carry egg metadata. If you want to make it possible to use the Debian-installed packages without duplication, you can do this by installing .egg-info files with the same base filename as the egg they would represent, placed in the site-packages directory where the package is installed. So, you might have something like "elementtree-1.0.2-py2.3.egg-info" in site-packages. The file's contents should be the package's PKG-INFO as created by the distutils. The setuptools runtime will find these files and thus know that it can access those packages as long as 'site-packages' is listed in sys.path. _______________________________________________ Distutils-SIG maillist - [email protected] http://mail.python.org/mailman/listinfo/distutils-sig
