There is clang/llvm 3.2 available, enabled for the archs:  amd64 i386 powerpc 
mips64 mips64el sparc sparc64

Reason for not using clang/llvm on OpenBSD still was the problem that some of 
the application were looking really 
weirdo when compiling -gui with > -OX and X>1.
But have to admit, the last time I tried was with clang 3.0 or so, things may 
have changed.
But I'm just installing new version, so 

GNUstep packages are available for macppc, i386, amd64. But when you want to 
develop, I'd recommend to install
the stuff from ports. First install the packages, to get all the dependencies 
(pkg_add -i gnustep-desktop)
Then remove all the packages again (pkg_delete gnustep-base gnustep-make 
gnustep-libobjc2)
Then put 

DEBUG=-g

in your /etc/mk.conf

and then install from ports: cd /usr/ports/x11/gnustep && make install
This will keep your sources around, and will compile everything with debug 
symbols, so you should be able
to thoroughly debug with gdb. I recommend installing gdb as a package too, and 
then use this.
This will not crash that often on you while debugging ;)
Also for my private development, I'm heavily leveraging the ports 
infrastructure in order to keep
my build environment clean.

Note, that all the packages are based on releases, so "lacking a bit" behind 
current development in subversion.
The long release cycles of the base libraries make it a bit harder to run 
bleeding edge ;)

If you have more questions or problems with GNUstep on OpenBSD, you may contact 
me privately.
I'm happy to hear about that, and help out.

cheers,
Sebastian
