Building clang for use with GNUstep

1) Build using the instructions here: http://clang.llvm.org/get_started.html

2) Once that's done, download the latest version of Hans Boehm's garbage collector here: http://www.hpl.hp.com/personal/Hans_Boehm/gc/

3) Untar, Build and install boehm-gc.... it should be gc-7.1.tar.gz
    build it with clang like so:
              ./configure CC=clang LD=gcc && make CC=clang LD=gcc
          make install
    NOTE: You only need to do step 2 & 3 if you want garbage collection, if not you can skip it.

4) Build gnustep-make like so and install it:

              ./configure CC=clang LD=gcc && make CC=clang LD=gcc

          make install

5) Build libobj2 and install it:

              make CC=clang CXX=clang++ LD=gcc

         make install

              

6) Build base, gui and back and install them:

         ./configure CC=clang CXX=clang++ LD=gcc && make CC=clang CXX=clang++ LD=gcc messages=yes

         su

         . /usr/GNUstep/System/Library/Makefiles/GNUstep.sh && make GNUSTEP_INSTALLATION_DOMAIN=SYSTEM install

That should be all there is too it.  Not much, but a few little details which might serve to make it enough of a pain to discourage some people.
