There is a chance you are experiencing a man-in-the-middle attack, but most
likely your system doesn't have the CA certificates needed for verification. For
information about OpenSSL certificates, see bit.ly/ruby-ssl. To connect without
using SSL, edit your Gemfile sources and change 'https' to 'http'.

Workaround for Semaphore regression on 2013-07-07/08, bundler missing for Ruby 1.9.2.

If your project is using Ruby 1.9.2, add these build setup commands to avoid the regression:

rbenv local 1.9.2-p320
gem install bundler --no-ri --no-rdoc

Update: regression has been fixed
