ghc-6.10.0.20081007 seg faults on Sparc

My attempt to build ghc-6.10.0.20081007 on a sparc created a stage2 compiler that seq-faults. I don't have much time (and no idea how) to continue:

cabal-bin: ghc version >=6.4 is required but the version of
/export/local2/home/maeder/haskell/ghc-6.10.0.20081007/ghc/stage2-inplace/ghc
could not be determined.
