Makes sure that ruby 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 $RUBY is not set (for example by running AC_CHECK_PROG or AC_PATH_PROG) the macro will fail.


  AC_PROG_RUBY_VERSION([1.8.0],[ ... ],[ ... ])

This will check to make sure that the ruby you have supports at least version 1.6.0.

NOTE: This macro uses the $RUBY variable to perform the check. AX_WITH_PROG([RUBY],[ruby],[VALUE-IF-NOT-FOUND],[PATH]) can be used to set that variable prior to running this macro. The $RUBY_VERSION variable will be valorized with the detected version.
