Hi Karl, the gnustep-nonfsf looks unlucky in its birth!
When I use the "Downloads" link I get: The web page you are trying to access doesn't exist on Savannah.If you think that there's a broken link on Savannah that must be repaired, file a support request, mentioning the URL you tried to access (/files/?group=gnustep-nonfsf).
The download area is enabled in the administration settins.Some files do exist. I recovered some of the tarballs available on GNA and uploaded them.
