The patch to add AC_PREREQ to AM_PATH_LISPDIR is necessary not to
prevent the failures Noah described, but simply to prevent users from
trying to use the macro with an Autoconf version that is too old and
does not cause `${datarootdir}' to be defined.  Even if that Autoconf
version is used consistenly, for both tracing from aclocal, and for
generating `configure'.

OK to apply the patch?

Cheers,
Ralf
