Subject: Re: [OMPI devel] Merging in the CPC work
From: Jeff Squyres (jsquyres_at_[hidden])

I had a linker error with the rdmacm library yesterday that I fixed
later, sorry.

Could you try it again? You'll need to svn up, re-autogen, etc. It
should be obvious whether I fixed it -- even trivial apps will work or
not work.

Thanks.
