IDN and WARNING: 'automake-1.14' is missing on your system.

[Jeffrey Walton]

I'm experiencing an configure error for IDN on three different
machines. The machines have a new M4, new Autoconf and Automake
1.15.1, but fail with:

/home/scripts/libidn-1.33/build-aux/missing: line 81: automake-1.14:
command not found
WARNING: 'automake-1.14' is missing on your system.
         You should only need it if you modified 'Makefile.am' or
         'configure.ac' or m4 files included by 'configure.ac'.
         The 'automake' program is part of the GNU Automake package:
         <http://www.gnu.org/software/automake>
         It also requires GNU Autoconf, GNU m4 and Perl in order to run:
         <http://www.gnu.org/software/autoconf>
         <http://www.gnu.org/software/m4/>
         <http://www.perl.org/>
