No, that was why I put that in there. The regression tests fail when  
I check out a clean trunk as well. Whether this is a problem just on  
OS X or a problem with the regressions, I'm really not too sure.

I just tried it on a linux box remotely and it failed as well. So it  
looks like a problem with the regressions.
