Apple separated the math library from the System framework a short
while before OS X 1.0 was released.
You need to recompile the RTS, which is tricky because the GMP library
in 4.08.1 is a bit difficult to compile on OS X.
Can I upload my replacement for libHSrts.a and libgmp.a, or the
complete tarball (~22M) somewhere ?  On Atze's page, maybe ?
Or on www.haskell.org ?

I've been working on the port to MacOS X.  As it is, GHC 5.00 will not
work even if you manage to compile it - the MachO binary architecture
requires some adjustments in the RTS.
A while ago I managed to get that working, but I stupidly lost some of
the patches.
I've been too busy to do it again recently, but I will have more time
by the end of the month.
