This port has been broken for years and no longer maintained by upstream.
Use net-im/rubygem-termtter instead. Rubygem earthquake and termtter were
originally developed by the same author and he no longer maintains both.
Now termtter is developed by community and still works.
Also, remove security/rubygem-jugyo_twtter_oauth. It is a fork of
twitter_oauth[1] and required only by net-im/rubygem-earthquake.
