My suggestion would be to simply require Automake 1.12 from every
developer, and avoid such compatibilities headaches (1.12 still
requires just Autoconf 2.62 and perl 5.6, so that your developers
won't be forced to upgrade other tools in addition to Automake
itself).

If you really *must* support both Automake 1.11 and 1.12: take a
look at the attached tarball; it should (hopefully) provide you
with enough inspiration to do so.
