The directory doesn't even need to exist. RubyGems will create it and
everything it needs inside it when you reference it, provided you have
permission to do so.

I use two tricks for this.
The frequently-used trick is to add the paths for the various
dependencies to the -I flag while working on the other dependent
project. RUBYLIB can also accomplish this.
The hardly-used trick is hoe's install_gem task.
Adding a way to load gems w/o being in a gem has been brought up
before, and I rejected the feature. It's much simpler to use -I or
RUBYLIB than to add a bunch of code to RubyGems to accomplish the same
