Hi, I tried to emerge "dev-lang/ghc-6.12.3" It fails with MAKEOPTS="-j9", but builds perfectly with "-j1". Is the buildlog necessary here?

Yeah, it's a known upstream issue: http://hackage.haskell.org/trac/ghc/ticket/3763 The workaround is to set lower parallel job count for make. *** This bug has been marked as a duplicate of bug 326347 ***
