Makes sure that perl supports the version indicated. If true the shell commands in ACTION-IF-TRUE are executed. If not the shell commands in ACTION-IF-FALSE are run. Note if $PERL is not set (for example by running AC_CHECK_PROG or AC_PATH_PROG), AC_CHECK_PROG(PERL, perl, perl) will be run.

Example:

 AC_PROG_PERL_VERSION(5.6.0)

This will check to make sure that the perl you have supports at least version 5.6.0.
