Adding the bin/ directory of the virtualenv (if you specify a virtualenv) as a path_prefix so that other programs that only exist in the virtualenv will be available to things being installed into said virtualenv. Classic example: installing gevent requires cython binary to be available, but if cython is in the virtualenv only it won't be found without this.
