Bundler could not find compatible versions for gem "builder":
  In Gemfile:
    signal_api (>= 0) ruby depends on
      builder (~> 3.0.0) ruby

    rails (= 3.0.0.rc) ruby depends on
      builder (2.1.2)

have a circular problem here. rails requires builder 2.1.2 and signal_api requires builder 3.0.0. any ideas? i can only include 1 builder gem in my Gemfile at the same time

Try installing it again, I just pushed a change that dropped the builder version down to 2.0.0.

The next rev of the gem will have builder removed as we'll just hit some JSON APIs on our side.

Ah, that's not going to work with ruby 1.9 - just got a build failure notification https://travis-ci.org/signal/signal-ruby/builds/5144383
