GHC 6.4.2 on OS X

[Peter Gammie]

Hello,

OK, if GHCi's linker can't cope with the extra symbols, then perhaps  
we can get rid of them.

Following the advice here:

http://lists.apple.com/archives/scitech/2005/Sep/msg00019.html

I  built my GHCi .o file like so:

GHCI_LD_OPTS += -L/usr/lib/ -lSystemStubs
...
$(LD) $(GHCI_LD_OPTS) -o h$$lib.o $(CUDD_LIB)/$$lib/lib$$lib.a;\

err... you get the idea: add that bit of linker magic to whatever  
you're already doing and those nasty symbols go away. I don't know if  
this is a general fix but it works for me.

cheers
peter
