Except... I can't find llvm on my system. 'locate llvm' doesn't

changed), that would be handy.
LLVM on Leopard is not an end-user or developer technology. That's
why you're not finding it.
On the other hand, I've found that LLVM is one of the easiest, most
straightforward Open Source projects that I've found when it comes
to building it straight from Subversion.
To check out and build LLVM for debugging straight from Subversion:
[Projects]% svn checkout http://llvm.org/svn/llvm-project/llvm/
trunk llvm
[Projects]% mkdir build
[Projects]% pushd build
[Projects/build]% ../llvm/configure --enable-targets=host-only
[Projects/build]% make -j 2
(Note: I've only done the above on Leopard.) You can also use a
packaged distribution from <http://llvm.org/>; LLVM 2.1 was just
released.
Or you can use MacPorts (www.macports.org) containing llvm (2.0
though). There you can just say 'sudo port install llvm', and that
does it. If llvm is the only thing you are looking for, then it is
probably not worth it to install MacPorts, but if you use other OSS
stuff, you could give it a try.
One other hint: LLVM is designed such that it can handle parallel
builds, so do a "make -j X" where X is the number of CPUs you
have. When doing the above on my 1st-generation 2GHz MacBook Pro,
a from-scratch "make -j 2" only takes about 5 minutes.
