Comment 23 for bug 339904

When installed whole set (new python2.6 and python-virtualenv) everything works fine. I had this fix made before last update and then due to some mirror sync problems i got only virtualenv.
I'm not sure if the change made to python2.6 was better than fixing virtualenv itself. Checking for "real_prefix" seems a bit hackish to me. But maybe that's only because when I choose a path I stick to it ;)
