Did you run the postinstall.rb script?

See http://rmagick.rubyforge.org/instal...

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

Try using it -- just because require returns false does not mean it
failed. The library's gemspec probably used autorequire.[1]

[1] and removed it. http://rubyforge.org/cgi-bin/viewcvs.cg...
rmagick.gemspec?root=rmagick&view=log

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.
