While dealing w/ GNU-vs-Berkeley Make issues, mentioned in passing that I wasn't able to autogen on my FreeBSD tester because the resulting configure failed. The specific failure I encountered was:
configure: error: No atomic primitives available for amd64-unknown-freebsd8.2

The problem boils down to the difference in the following:

$ /usr/local/share/autoconf-2.68/config.guess
amd64-unknown-freebsd8.2
$ openmpi-1.5.5rc1/config/config.guess
x86_64-unknown-freebsd8.2

These differ in the arch identifier, which then causes (at least) opal/config/opal_config_asm.m4 to decide there is no atomics support for the (unknown) architecture. 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.

The basic problem is that this system's config.guess is ancient (timestamp='2003-07-02') despite the recent autoconf-2.68. I suggest that autogen.sh should include logic to keep the NEWER of the config/config.guess and the one that "automake --copy" wishes to install.

While looking into this I also noted something "odd" in autogen.sh:
Why is ompi_autoconf_version="2.59" when there is ALSO a check for 2.60 or later?

Note that I don't think this is worth fixing for 1.5.5.
