Currently, the --no-install option to `bundle package` is totally
ignored for git sources. This can have very strange effects if you have:
- a git-sourced gem,
- with native extensions,
- whose extconf.rb script depends on another gem,
- which is installed from Rubygems in the gemfile.
In that circumstance, `bundle package --no-install --all` will download
the Rubygems dependencies to `vendor/cache` but NOT install them. It
will also check out the git gems to `vendor/cache` (good), and attempt
to build their native extensions (bad!).
The native extension build will fail because the extconf.rb script crashes,
since the dependency it needs is missing.
I implemented a fix for this in `source/git.rb`, since this is analogous
to what's happening in `source/rubygems.rb`. I do admit though the whole
thing is a little strange though - an "install" method that.... proceeds
to look at a global flag to not install anything.
Add test to confirm cache respects the --no-install flag
