Was someone able to build ghc 6.8.2 on PPC with OS X 10.4 (Tiger) ? I had no problems to build the 6.8.1 but with 6.8.2, I get the error:

This is a new bug in 6.8.2 that we discovered just before Christmas: http://hackage.haskell.org/trac/ghc/ticket/2011 the workaround is simple: just make clean in libraries/base. Cheers, Simon
