Hi Mo,

There are 3 solutions:

1) Always use Bundler provided by Fedora which will works as it should.
2) Force Ruby and RubyGems upstream to properly support FHS. I already 
provided patches [1] but I need your support.
3) Revert the customized behavior of RubyGems for /usr/local

I strongly disagree with point 3. You have choice, either you broke some 
Ruby users expectations or you broke the rules given by FHS. You can't 
have both ATM. It would be nice if you could help to stir Ruby and its 
community in correct directions instead of promoting bad practices in 
the name of "often practised in the upstream ruby community". I would 
really appreciate if you could weight in and send your comments upstream 
[1]. Bundler upstream may follow, the patch is ready ....
