It looks like the "uname -o" that was added into OMPI.pm is problematic on OS X.

What does client/whatami/whatami return on the platforms that you care about? I.e., can we re-write this chunk of code in MPI/Install/ OMPI.pm to use whatami output:

    my $sys_type=`uname -o`;
    if(($sys_type =~ /cygwin/i || $sys_type =~ /msys/i) &&
        $config->{compiler_name} eq "microsoft") {
        $install = MTT::Common::Cmake::Install($gnu);
    } else {
        $install = MTT::Common::GNU_Install::Install($gnu);
    }
