[Gm2] Mac OS X Intel Update

[Michael Lambert]

Using a CVS update at about 0030 GMT, things are looking still better  
on Mac OS X Intel:

                === gm2 Summary ===

# of expected passes            6246
# of unexpected failures        48
# of unresolved testcases       18

I still haven't figured out how to make the tests work (ie, find  
libstdc++) without doing a 'make install' before running the tests.
