Works:
irb(main):001:0> require "openssl"
=> true
irb(main):002:0>


Doesn't work:
irb(main):001:0> require "puppet/network/xmlrpc/client"
Puppet::Error: You must have the Ruby openssl library installed
        from P:/pfm/puppet/lib/puppet/sslcertificates.rb:5
        from P:/pfm/puppet/lib/puppet/network/xmlrpc/client.rb:1:in `require'
        from P:/pfm/puppet/lib/puppet/network/xmlrpc/client.rb:1
        from (irb):1:in `require'
        from (irb):1
irb(main):002:0> require "openssl"
=> false
irb(main):003:0>

Actually, even shorter:

irb(main):001:0> require 'puppet'
=> true
irb(main):002:0> require 'openssl'
=> false
