[openfabrics-ewg] problems running MVAPICH on OFED 1.1 rc6 with SLES10 x86_64

[Pavel Shamis (Pasha)]

On some of our SUSE 10 machines i found the 127.0.0.2 ip,
but it was pointing to some random Linux site (linux.org)
and has no effect on mpi runs.
In you case the ip point to _real_ machine, it very strange.
