--disable-ruby is no longer needed, from the upstream NEWS file:
Due to lack of maintenance the Ruby bindings for Broccoli are now
deprecated, and the build process no longer includes them by
default. For the time being, they can still be enabled by
configuring with —enable-ruby, however we plan to remove Broccoli’s
Ruby support with the next Bro release.
