You can do all of the above now.  Just use the -m option to 
easy_install when you eggs to the non-site directory, and make sure 
that you add the directory to sys.path *before* importing 
pkg_resources.  Or, if you can't do that, do this:

     pkg_resources.working_set.add_entry(directory_just_added_to_sys_path)

This will allow pkg_resources to find eggs in that directory when you 
use require().

My guess is that you're probably importing pkg_resources before you 
add your egg directory to sys.path.  If not, please post code to show 
what you're doing.  You should be able to do exactly what you 
specified above, without any changes to setuptools or pkg_resources.
