Etienne  Mollier suggested to edit the configure.ac file of FOX and put 
there  near line 57 CXXFLAGS="-O -g"


Then I run  autoconf  (version is 2.69) and then I run ./configure 
--enable-debug --enable-release, but make fails:

rimski.x86_64 src/X11/fox-1.7.79 20:27 .0 % make
CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/bash 
/usr/src/X11/fox-1.7.79/missing aclocal-1.15
/usr/src/X11/fox-1.7.79/missing: line 81: aclocal-1.15: command not found
WARNING: 'aclocal-1.15' is missing on your system.
          You should only need it if you modified 'acinclude.m4' or
          'configure.ac' or m4 files included by 'configure.ac'.
          The 'aclocal' 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/>

Thanks for your help
