rubyforge.org shutdown on May 15, 2014. This commit accounts for that by doing several things: - Deprecate ruby that had only rubyforge.org as MASTER_SITES (and so are now only fetchable via our cache) - Deprecate ports that depend on those - Update the WWW pkg-descr line that points to rubyforge.org for rubygem ports (which are still fetchable from rubygems.org) The next step will be to remove rubyforge.org from bsd.sites.mk, after these deprecated ports are deleted. Phabric: D591 With hat: ruby Approved by: portmgr (because of committing to unstaged graphics/mingplot port)
