In my case I followed the guidelines in the top level README of 
Erlang/OTP, which exactly mirrors the OS X documentation, and it works 
perfectly. I would be a bit concerned about using non-standard ways of 
linking shared libs for OS X.

Extract of OTP README follows:

"If you develop linked in drivers (shared library) you need to link
using "cc" and the flags "-bundle -flat_namespace -undefined
suppress". You also include "-fno-common" in CFLAGS when
compiling. Use ".so" as the library suffix."
