Terrific!

Just tested a build, it seems to set the link properly, thanks very
much.  Do you have a timetable for the release of 1.5.x?

I'm attaching a simple and working patch for the 1.4.1 package in case
it will be a while.  The -Wl,-z,defs checks the library to make sure it
links to all of the libraries it needs, but is not portable.

Those checks also indicated that the MPI C++ library needs to link to
the stdc++ library, so I added that link to the patch for 1.4.1 as well.
(1.5 has the stdc++ link already.)

Thanks very much,
Adam
