Respect BUNDLER_GEMFILE

[chriseppstein]

My default gemfile is for setting up a development environment. which means it includes all kinds of irrelevant testing and development gems. I made a new gemfile but setting BUNDLER_GEMFILE didn't cause it to be used.

As a workaround I can make my gemfile aware of some other env variable.

This seems good. We probably just hardcoded Gemfile in.

Actually, see #8, I'm not sure BUNDLER_GEMFILE is the right thing to use for building the package. I think there needs to be two gemfiles.

Old issue, I know, but FWIW: Currently in bundler/master the environment variable is BUNDLE_GEMFILE, not BUNDLER_GEMFILE (no R). Don't know if that will help you, but it's worth a shot.
