Running with the --backtrace flag shows that the error happens when 
trying to apply "each" to the dependencies.  The new spec code sets up 
dependencies to be initialized to the default value of [].

However, Rake has no dependencies in the gem file.  When the rake spec 
is read by YAML, do we do anything to insure that dependencies != nil 
after loading by YAML.

That's where I would start looking.
