Sorry for the confusion. I am not building OpenMPI from the SVN source. I downloaded the 1.8 tarball and did configure, and that is what failed. I was surprised that it didn't work on a vanilla Redhat Enterprise Linux 6, out of the box operating system installation.
The error message suggested that I try autoreconf, so I tried it.
I can try the autogen.sh script and see if that fixes it, but I'm noticing another thread right now where Jeff is saying that shouldn't be necessary.

Don't run "autoreconf" by hand, make sure to run the "./autogen.sh" script that is packaged with OMPI. It will also check your versions and warn you if they are out of date.
Do you need to build OMPI from the SVN source? Or would a (pre-autogen'ed) release tarball work for you?
