This is effectively a cherry-pick of e173f9b. Somehow we lost one of the most critical parameter allowing the PML to decide how to order the different interconnects. Bring it back!

@jsquyres - i dont know if it is related to this failure, but today we upgraded libtool from 2.4.3 to 2.4.5 version on this server. |
Yes, it definitely is. We have not resolved open-mpi/ompi#366 and open-mpi/ompi#311 yet. I.e., OMPI does not yet work with LT 2.4.5. |
can it be detected at configure time and disable tldl if > 2.4.5? |
It's not actually a problem with libltdl. See the link off open-mpi/ompi#311 for details. Easiest to downgrade libtool. |
retest this please |
back to libtool 2.4.3 |
