OMPI has a long, deep history with the GNU Autotools. It's a very long, complicated story, but the high points are:
1. The GNU Autotools community has given us very good support over the years.
2. The GNU Autotools support all compilers that we want to support, including shared library support (others did not, back in 2004 when we started OMPI).
3. The GNU Autotools can fully bootstrap a tarball such that the end user does not need to have the GNU Autotools installed to build an OMPI tarball.
#2 and #3 were the most important reasons back in the beginning of the project.
Periodically, we have looked at other tools over the years because the GNU Autootols are far from perfect, too (scons, cmake, etc.). The other tools either still failed #2 or #3, or were not enough of an improvement to justify the time/effort to re-write OMPI's configure/build system.
To be clear: we'd need a *very* strong reason to move to another toolchain at this point.
