OK, replacing that libgmp with a custom-built version fixed my
standalone GCD.hs example.  So that confirms the problem.

Unfortunately, that doesn't fix it for me; my real issue is that ghc
iself is getting the illegal instruction error, in the middle of
compiling haddock-0.9.  And since ghc is statically linked to libgmp,
it can't use the replacement lib for itself.  (Ironic, since
statically linking gmp is supposed to make installation _easier_ :-)
It's not a big problem for me, though; one of the ghc-6.8.2
distributions should work fine, and I can use them to build 6.8.3
myself.

Now that we've confirmed it, can someone please update the 6.8.3
downloads page  (Replacing "PowerPC" with "PowerPC G5", perhaps)?

Thanks,
