Comment(by batterseapower):

 The -lfoo syntax works fine for me with GHC, and I have never used -dylib-
 install-name (I'm on OS X). That said, I have not tried your particular
 example because you do not provide the code for your various hs/c files.

 The problem you have in that Haskell Cafe thread is just because you have
 both charm.hs and charm.c, both of which will produce a file called
 charm.o. It looks like the charm.o from charm.c has overwritten the older
 one, which explains why the duplicate symbol error (from linking charm.o
 twice) mentions _Charm_getWidth_info.
