Gemfile.lock should be in the original control, and, I think, you see a warning to the hero that Gemfile.lock will appear soon. What are you doing then?
It's not all black, my collaborators are as bad as you, stuck on windows;) Some use Linux, others Mac. Our Gemfile.lock is as follows
GEM remote: http://rubygems.org/ specs: ... sqlite3-ruby (1.3.1) sqlite3-ruby (1.3.1-x86-mingw32)
Heroku, on the other hand, ignores sqlite3, so this might not be the best example. What pearl are you fighting?
I suggest you try manually inserting a gem with x86, as in the example above. Hope this helps ...
