commit a3b413eee36959af8895d2b434911c28e761fc81
Author: David M. Lee <dlee at digium.com>

    Fixed Apple module loading to prefer .so to .dylib.
    
    For Mac OSX, there's a distinction between shared libraries (.dylib)
    and loadable modules (.so).  While things work loading shared libraries
    instead of modules, it causes complications for folks using CMake to
    build their modules.
    * If they build as a module, then it has the .so extension and IceBox
      won't load it.
    * If they build as a library, now IceBbox will load it, but a Windows
      build will build it as a library, and generate a .LIB file that you
      really don't want.
