RUBY_PLATFORM is pretty good, but don't forget about the 'rbconfig'
module either.
puts RUBY_PLATFORM # => 'i386-linux'
require 'rbconfig'
puts Config::CONFIG['target_cpu'] # => 'i386'
puts Config::CONFIG['target_os'] # => 'linux'
puts Config::CONFIG['host_cpu'] # => 'i686'
puts Config::CONFIG['host_os'] # => 'linux-gnu'
good stuff there.

Plug around in the 'rbconfig' module, see if any of the items in there
work better.
