[ewg] [mpich2-dev] Problems with mvapich2-1.5.1 - shared library is missing hwloc_* functions.

[Dhabaleswar Panda]

Dave and Mike - Jonathan posted a follow-up reply on this already. The
latest 1.5.1 version uploaded to OFED during the weekend has solved this
problem. The OFED daily build has already this fix. This latest MVAPICH2
version (1.5.1) is planned to be released tomorrow.

Mike - Please feel free to post your MVAPICH2 related questions to the
MVAPICH mailing list.

Thanks,

DK
