/builddir/build/BUILD/pappl-retrofit-1.0b2-build/pappl-retrofit-1.0b2/missing: line 81: automake-1.16: command not found
WARNING: 'automake-1.16' 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:
         <https://www.gnu.org/software/automake>
         It also requires GNU Autoconf, GNU m4 and Perl in order to run:
         <https://www.gnu.org/software/autoconf>
         <https://www.gnu.org/software/m4/>
         <https://www.perl.org/>
make: *** [Makefile:565: Makefile.in] Error 127]: [Make reports automake-1.16 is missing on the system.]

Issue: automake-1.16 was used in configure script in the project.
Resolution: Regenerate configure script at start of build phase in SPEC file, f.e. via autogen.sh, autoreconf etc. and rebuild the package.
