No, probably not. Plus, I wouldn't recommend actually using this,
since I plan to deprecate GemInstaller in favor of Bundler. I was
just giving it as an example of your request, so I could point out how
Bundler is superior.

Not sure what you mean by malformed dependencies. In the rebuild
case, you would just install ruby and rubygems, then run Bundler for
the specified project/environment.

Yes. Bundler resolves the entire dependency tree at development-time.
Currently you persist this by checking in the selected .gem files in
the cache dir. Future versions will allow you to persist this without
having to check in .gem files.
