Hi, guys

  I have the following code copied from the ruby-ffi github page. I have Xcode installed. tested both in ruby ruby-1.8.7-p352 [ i686 ] and ruby-1.9.2-p180 [ x86_64 ]

  but got the error: 

  gems/ffi-1.0.11/lib/ffi/library.rb:121:in `block in ffi_lib': Could not open library 'c': dlopen(c, 5): image not found. (LoadError)

Could not open library 'libc.dylib': dlopen(libc.dylib, 5): image not found

  the code:

  require 'rubygems'

  require 'ffi'

  module MyLib

    extend FFI::Library

    ffi_lib 'c'

    attach_function :puts, [ :string ], :int

  end

  MyLib.puts 'Hello boys using libc!'
