Yes. I hinted at the problem in my submission as I am seeing it in the
same way. For some reason autoconf does not pick up pkgconf's pkg.m4 and
does not substitute PKG_CHECK_MODULES. I suggested that you may need to
vendor pkg.m4 into aclocal.m4. It is not clear to me when autoconf
searches /usr/share/aclocal and when not. It also appears to not read
acinclude.m4 here.
