Stale WWW entries in your ports

Dear Maintainer

The following ports contain a stale reference to a project website or
other relevant resource in the WWW entry of the ports' Makefiles:

devel/rubygem-cloudfiles	http://www.rackspacecloud.com/cloud_hosting_products/files
devel/rubygem-slim     	http://slim-lang.com/
japanese/ruby-uconv    	http://www.yoshidam.net/Ruby.html

Please replace the stale WWW entry with one that provides information
that users of the port or package might consider useful (e.g. a project
website, configuration examples, further reading).
