Charm++ parallel programming system

[Evan Ramos <evan AT hpccharm.com>]

I updated the patch to account for the possibility of a full pathname being prepended to the compiler name, as your mpicxx is returning. I think it should fix the problem.

Actually, I did NOT exactly built the 2nd time using exactly the same
build command line, so I just re-tested this with the same command line
as the first time, and attach the output. The build line was this time
(as the first time):

./build charm++ mpi-darwin-x86_64

However, I think this is independent of the problem, because it appears
to break the same way.

Thanks,
J
