This may be a clang versus gcc issue, but I'm not certain.

I'm getting the same error on OSX 10.11.4 (or at least this part of it):

Undefined symbols for architecture x86_64:

It's attempting to install version 2.0.12 with Ruby 2.3.0

Which version of libassuan do you have installed ? I can install ruby-gpgme v1.0.7 on FreeBSD 10.3-RELEASE with libassuan v2.4.2 alright.

Ruby interpreter was /usr/local/rvm/rubies/ruby-2.0.0-p353/bin/ruby

On OS X running brew upgrade gnupg2 installed the missing dependencies for me.
