[Haskell-cafe] Bulding a library for C users on OS X

I'm trying to call a Haskell function from C, on OS X. There's an
excellent post  by Tomáš Janoušek that explains how to do this on
Linux. However, on OS X, it's different. First of all, it looks like
the -no-hs-main flag is ignored, because I get the following error:
> ghc -O2 --make -no-hs-main -optl '-shared' -optc '-
DMODULE=Test' -o Test.so Test.hs module_init.c
> [1 of 1] Compiling Main ( Test.hs, Test.o )
> Test.hs:1:0: The function `main' is not defined in module `Main'
Second, I learned  that I have to pass in different flags on OS X,
but unfortunately, GHC still wants me to have main. I'm probably doing
something wrong here, is there anyone who can give me some pointers?
(no pun intended).
I'm running GHC 6.10.2 on Leopard.
