I updated trac 3047. Thanks for the additional patch: "mpirun -H <remotenode> hostname" now works.

I'm quitting for the day, but happened to notice that all our v1.5 MTT runs are failing

even just "hostname" on a remote node, the job fails with

orted: Command not found

I get this problem whether I include "--prefix $OPAL_PREFIX" or not.

Looking at recent putbacks, I see r26132 pulls in r26081 to fix #3047.  
According to both the trac ticket and 
http://www.open-mpi.org/community/lists/devel/2012/03/10672.php , r26081 alone 
isn't enough, but... whatever, I'm going to bed.  It does seem like r26132 
isn't quite right.
