FFI callback segfaults on PPC

ghc-pkg has been segfaulting ever since I installed ghc-6.12.1.20100330 on my G5 PowerPC running gentoo 32-bit userland; current state:

/usr/local/packages/ghc-6.12.1.20100330/lib/ghc-6.12.1.20100330/package.conf.d
   Cabal-1.8.0.3
   QuickCheck-2.1.0.3
   array-0.3.0.0
   base-3.0.3.2
   base-4.2.0.1
   bin-package-db-0.0.0.0
   binary-0.5.0.2
   bytestring-0.9.1.6
   containers-0.3.0.0
   directory-1.0.1.1
   Segmentation fault

(Now, trying to install zlib, I also get:

 ./Setup configure --prefix=/usr/local/packages/ghc-6.12.1.20100330 -p
Configuring zlib-0.5.2.0...
Setup: failed to parse output of 'ghc-pkg dump'

although I can see nothing wrong with the output of 'ghc-pkg dump' — reported under Bug 559 in the Cabal trac.)
