Crap, so cabal-install is totally broken with 6.8.1. cabal-install is  
trying to find ld even before it has started to install a package. We  
could cd to $tmpdir/something, and run findCompiler there. Nasty hack  
workaround though. I guess we need to start testing cabal-install  
with Cabal releases before they are released...
