I’m also on Mavericks and I have a fix.  Unfortunately it is unlikely that I can push it to hsx25 given we are so late in the 8 cycle.  Might have to wait until we open the 9 repositories.

Here is the fix.  It also adds the missing optimization-level downgrade for loopTransform.o.  I can push this to the Graal repository if you want.
