I have a patch for the dynamic linker in MacOS X, which permit to load 
the extension bundle linked dynamically against optional library 
(libiconv, readline and gdbm). The Patch is not from me, but from 
"Peter O'Gorman" <peter@pogma.com>. We worked around the issue when I 
tried to import the ruby 1.7 dev version in the darwinport tree.

The patch is in attachment and is included in the message.
