Error upgrading libltdl

[Clint Olsen]

I was trying to do a portupgrade of various ports and ran across this
failure:

===>  Building for libltdl-1.5.22_1
cd . && /bin/sh /usr/ports/devel/libltdl15/work/libtool-1.5.22/libltdl/missing --run aclocal-1.9a 
aclocal-1.9a: not found
WARNING: `aclocal-1.9a' is missing on your system.  You should only need it if
         you modified `acinclude.m4' or `configure.ac'.  You might want
         to install the `Automake' and `Perl' packages.  Grab them from
         any GNU archive site.
cd . && /bin/sh /usr/ports/devel/libltdl15/work/libtool-1.5.22/libltdl/missing --run autoheader

I appear to have autoconf/automake already installed and with the
appropriate versions.
