Can't compile GHC 6.8.2

[Barney Stratford]

There's good news and bad news. The good news is that the compilation of
my shiny almost-new GHC is complete. The bad news is, it won't link.
It's grumbling about 

ld:
/System/Fink/src/fink.build/ghc-6.8.2-1/ghc-6.8.2/rts/libHSrts.a(PrimOps.o)
has external relocation entries in non-writable section (__TEXT,__text)
for symbols:
___gmpn_cmp
___gmpn_gcd_1
___gmpz_fdiv_qr
___gmpz_init
___gmpz_tdiv_qr
___gmpz_com
___gmpz_xor
___gmpz_ior
___gmpz_and
___gmpz_divexact
___gmpz_tdiv_r
___gmpz_tdiv_q
___gmpz_gcd
___gmpz_mul
___gmpz_sub
___gmpz_add

Looking through the archives, it seems like this is an old favourite bug
rearing its ugly head again. The suggested remedy of commenting out the
line reading "SRC_HC_OPTS += -fvia-C" in the Makefile won't work, as
that line isn't there anyway. The manpage for ld has an option
"-read_only_relocs warning" that looks like it might suppress this
problem, but I don't fully understand what it's doing.

What would you suggest?

Cheers,
Barney.
