Following the instructions in bug 629459, comment #3, we need to build clang on a mac machine and deploy it with puppet.
Using moz2-darwin10-slave04 to build, under ~/src/clang
Initial compilation took 62m37.659s

normal build and try slaves are now picking this up. it will be a few hours before they all get it. you should be able to set /tools/clang-2.9/bin/clang as your compiler in your mozconfig for try.
Looks like it is not available on this on: http://firstname.lastname@example.org/try-macosx64-debug/try-macosx64-debug-build234.txt.gz
ignore me, I think I found the problem
OK, this is a real problem: http://tinderbox.mozilla.org/showlog.cgi?log=Try/1305222441.1305222720.13622.gz&fulltext=1 The log has: /tools/clang-2.9/bin/clang: No such file or directory i386-apple-darwin9.2.0
We need it on 10.5 machines as well

built clang-2.9.dmg on moz2-darwin9-slave03:src/clang
Looks like this is getting deployed ok. Probably take a few hours before the majority of the machines have it.
