I solved the problem.
I was assuming that since I was duplicating the standard Rails dir
structure in my gem that Rails would load files automatically if their
parent dir was on $LOAD_PATH. I was wrong. From now on, I will only
assume that Rails is loading only one file automatically (rails/
init.rb).
My gem is called Sitecontrol... I just added a require 'sitecontrol/
config/routes' from my gem's initial lib file (sitecontrol.rb) to the
extra routes.rb file I added.
