Error when running jekyll docker container with boot2docker on Mac

Question

I am running docker on my MBP (Yosemite 10.10.3) with boot2docker (v1.6.2). When I try to run docker run --rm -v "$PWD:/src" grahamc/jekyll build (without sudo) I got the following error:

twer$ $(boot2docker shellinit 2> /dev/null)
twer$ docker run --rm -v "$PWD:/src" grahamc/jekyll build
/usr/local/bundle/gems/bundler-1.9.9/lib/bundler/spec_set.rb:92:in `block in materialize': Could not find coffee-script-source-1.9.1 in any of the sources (Bundler::GemNotFound)

Please help.

It's working fine on my machine:

$ docker run --rm -v "$PWD:/src" -p 4000:4000 grahamc/jekyll serve -H 0.0.0.0
Configuration file: /src/_config.yml
            Source: /src
       Destination: /src/_site
      Generating...
     Build Warning: Layout 'nil' requested in atom.xml does not exist.
     Build Warning: Layout 'none' requested in feed.xml does not exist.
                    done.
 Auto-regeneration: enabled for '/src'
Configuration file: /src/_config.yml
    Server address: http://0.0.0.0:4000/
  Server running... press ctrl-c to stop.

My best guess is that you have a Gemfile in your source code.
