Did you run the postinstall.rb script?

Did you set up the RubyGems environment?

The ‘false’ return value from require is meaningless when you’re using  
RubyGems. Try this:

require ‘rubygems’  
require ‘RMagick’

puts Magick::Long\_version

Require returning ‘false’ does not mean that it has failed. It just  
means that the library has been already loaded. If the RMagick gem does  
an autorequire on the RMagick file, then that file will be loaded during  
the activation of the RMagick gem, meaning that by the time your require  
finishes, the file is indeed loaded.
