To be more exact: The missing macros are from libtool, not
autoconf/automake. Perhaps you don't have libtool installed? The output
of *all* command requested below would be helpful.

Almost all of the clutter in the logfile has nothing to do with your
problem, it is caused by aclocal recursively picking up autoconf macros
from other packages which are not well-maintained. They are warnings
about things which are handled slightly different and in a stricter way
nowadays. It's very annoying that distributors/maintainers don't fix
these warnings (FreeBSD is no exception here, e.g. SuSE is guilty of
this, too), but they are harmless. Fixing this while maintaining
backwards compatibility with older autotools is a bit tricky, but
perfectly doable. OTOH, "normal" users will never see these warnings,
only package maintainers and people building source distributions.

Cheers,
