Subject: Re: [OMPI devel] generates broken configure on FreeBSD-8.2

Paul -

Are you running autogen from the tarballs in your testing? You probably shouldn't - we have users just run configure and make. We also bootstrap the tarballs w the most recent config.sub and .guess (i.e., more recent than what comes w the most recent Autotools).

Sent from my phone. No type good.

The included hwloc also appears unhappy w/ arch=amd64, but at least that is non-fatal. I cannot (yet?) say what else is broken due to this disagreement in system tuple. I can say that adding "|amd64-*" in the appropriate spot in opal/config/opal_config_asm.m4 is sufficient to get past the configure failure.
