edd_at_ron:~> ldd /usr/lib/openmpi/mca_osc_pt2pt.so
        libnsl.so.1 => /lib/i686/cmov/libnsl.so.1 (0xb7f9a000)
        libutil.so.1 => /lib/i686/cmov/libutil.so.1 (0xb7f96000)

Not that I can tell. What else could I test? The build-logs don't reveal
anything fishy -- all pt2pt occurrences look fine. The build itself
proceeded fine (and this was the Debian package build I then uplod)
