Instructions for building clang from svn are here:

http://clang.llvm.org/get_started.html

I've not tested it on GNU/Linux.  My development platform is FreeBSD,  
but I believe it should all be similar.

Most of GNUstep builds with clang / llvm with the version I have.  I  
can send you my diff if you're interested, but hopefully they should  
all be going into the main repository in the next week or so (they're  
currently pending code review).  I won't post the diff to the list  
since it's around 130KB.
