ghc 6.0.1 and Mac OS X 10.2.6 build

Hi,

I've built ghc 6.0.1 under OS X 10.2.6 and have a curious problem with 
ghci.
ghc seems to work fine, but ghci give me an error. I should note that 
I've done
the build without Wolfgang's HaskellSupportFramework, by setting the 
include
and library paths in build.mk. This is more compatible with the 
automated packing
scheme of DarwinPorts.

This is what I see:

bash-2.05a$ ghci

Please report it as a compiler bug to glasgow-haskell-bugs@xxxxxxxxxxx,
or http://sourceforge.net/projects/ghc/.


bash-2.05a$


The error message comes from ghc/rts/Linker.c. Apparently dlsym couldn't
find the symbol _free from libSystem.

I suspect that doing things this way I have to link HSbase_cbits.o (and 
its siblings)
with -lSystem, Is that correct, or is this a different problem? If it's 
obscure I have a
way I could build a new Framework out of the installed package 
dependencies,
but it's somewhat messy.

Thanks.
