rubygem databases conflicting file placement

[Dewayne Geraghty]

As there have been a few updates to rubygem ports occurring, would someone be able to look into why these ports:
/usr/ports/databases/rubygem-arel3  2014-08-27
/usr/ports/databases/rubygem-activerecord 2015-04-03
place files into the same location and cause conflict?  I've added the dates of when they were last modified.

They're preventing metasploit from being built.

Please refer to the last entry in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=199107

Thank-you.
Dewayne.
