Take the latest-and greatest unstable, unreleased GNU Hurd from Debian (this will give you an improved libc and thread library that doesn't require certain hacks to make some un-Posix code to work). Install it (and cross your fingers). Install of course the objective-c compiler. Install the necessary dependencies (libxml2, libpng, ffcall) witht ehir developer headers.
Then get the latest GNUstep. Configure and install make, base, gui and make. I used the xlib backend.
Now some caveats: the base library needs to be hacked. More specifically, after you have run configure, modify Sources/config.h and define BROKEN_SO_REUSEADDR to 1. Also I experience some troubles with the daemons of GNUstep, not only on HURD but elsewhere too, thus manually start gdomap and gdnc.
Now you are ready to start your applications! install one, run "make_services" so that it is registered and then launch it with "openapp NAME" or "gopen NAME.app". Inside the gnustep repository there is the workspace manager (a must have, but currently it crashes here) a small RTF text editor Ink (favourite small app to test if GNUstep is working...) and there are many nice applications in the GAP project and from Backbone.
If someone doesn't believe, check the screenshot... FTP is connected to the gnustep site and Ink is typing well...
So the edges are a bit rough yet. But it starts to be there, I'm excited.
