Not, it's not odd, it means that, because you put "require 'super'" at the
top of the sub class file, the sub class found the super class, and you now
have an new problem. The new problem is the absence of:

require 'activerecord'

at the top of the super class file. 

Before, the sub class couldn't find a definition for 'super'. Now super
can't find a definition for 'activerecord'.

Each Ruby source file that requires information from outside itself ... must
say so.
