I was rather frustrated when I tried to find out how to create the
linked in drivers. I *think* I got it working, I haven't got the OSX
machine into our daily build and test yet.

>From the erts/configure.in

                DED_LDFLAGS="-bundle -undefined suppress"
                DED_CFLAGS="$DED_CFLAGS -fno-common"

>From our test server configure script

    Darwin*)
        SHLIB_CFLAGS="-fno-common"
        SHLIB_LD="cc -bundle -undefined suppress"
        SHLIB_SUFFIX=".so"
        ;;

I don't remember exactly but I think I failed to link with "ld"
and use "cc" to link.
