Per Dave's comment: note that running autogen.pl (or autogen.sh -- they're sym links to the same thing) is *only* necessary for SVN/hg/git checkouts of Open MPI.
You should *not* run autogen.pl in an expanded Open MPI tarball unless you really know what you're doing (e.g., you made a change to Open MPI that requires re-generating the GNU Autotools scripts). Meaning: if you are expanding an Open MPI tarball, there's usually no reason to run autogen.pl -- just run configure and make.
Sidenote: if you don't run autogen.pl, then it doesn't matter what version of GNU Autotools you have installed. The Open MPI tarballs are pre-bootstrapped with the Right versions of the GNU Autotools so that end users don't have to worry about this kind of junk. Having the Right versions of GNU Autotools is generally only an issue for Open MPI developers.
