Ruby 1.8 has been deprecated, you should at least use 1.9.1.

Apparently Ubuntu's ruby is somewhat different from everyone else's:

Can you run "irb" and check the methods available for the File class?

Adding a line "require 'pathname'" to each of the four affected source files 
should fix the issue even for Ubuntu users. Can someone please confirm?

In a different app that suffered from this, I also had to swizzle things around 
a bit:

-$path = File.dirname(File.realpath(__FILE__))
+$path = File.dirname(Pathname.new(__FILE__).realpath)
