A very simple macro (maybe still buggy) that should be useful to look
for bison:

http://autoconf-archive.cryp.to/ax_prog_bison.html

You could adapt (it should be really easy) the following macro to
extract the bison version:

http://autoconf-archive.cryp.to/ax_prog_perl_version.html

And finally compare that version with the required version using the
following one:

http://autoconf-archive.cryp.to/ax_compare_version.html

Cheers,
Francesco
