I use RVM and have some legacy projects where I use Ruby 1.8.7, rails 2.3.x, rspec 1.3.0 and rspec-rails 1.3.2. But after installing Ruby 1.9.2 and some gems rvm is messing up the Gem paths for 1.9.2 and my 1.8.7 gemset:

When I run my specs with rake I get the following error:

```
"\"/home/vermelho/.rvm/gems/ruby-1.8.7-p302@rails2/gems/paperclip-2.3.3/data/paperclip\""
config.load_paths is deprecated and removed in Rails 3, please use autoload_paths instead

```

In the gemset I currently use rspec 2 is not installed, and my current ruby installation and gemset should know nothing about gems from another ruby installation, right?
