AX_WITH_RUBY([VALUE-IF-NOT-FOUND],[PATH])
Locates an installed Ruby binary, placing the result in the precious variable $RUBY. Accepts a present $RUBY, then --with-ruby, and failing that searches for ruby in the given path (which defaults to the system path). If ruby is found, $RUBY is set to the full path of the binary; if it is not found $RUBY is set to VALUE-IF-NOT-FOUND if provided, unchanged otherwise.
A typical use could be the following one:
