Thanks for explaining this, Nick, and in fact the problem was
self-inflicted as I was installing the prerelease Automake versions to a
different prefix than libtool (and the base automake) without taking steps
to help aclocal find the libtool macro definitions.

After installing Libtool to the same prefix as the prerelease Automake, the
problem disappeared.

Cheers,
