Subject: [OMPI devel] More on OMPI on MacOS 10.4/ppc [WORK AROUND]

As I already discover (see, MacOS
10.4 is NOT listed as a supported platform any longer. So, this message
is really just for the archives.

 From "man ld" on a MacOS 10.4 system (x86 or ppc):

The last sentence of that seems like a good starting point for why the
behaviors I see on ppc and x86 differ.
So, before configuring OMPI (tarball 1.7a1r25937 or 1.5.5rc2r25933) I did

And, everything worked!
Both branches had the previously described errors w/o this env var, but
now both work fine.

So, anybody in need of OMPI on MacOS 10.4/ppc now has a work-around.
