validate in build tree fails due to problem copying haddock resources to inplace

I setup my build tree using the instructions here http://hackage.haskell.org/trac/ghc/wiki/Building/Using . After booting and configuring, I ran "sh validate" which eventually halted on the following command with the following error:

haddock: internal error: /Users/andreas/repos/temp-ghc-3/ghc-build/inplace/lib/html/Ocean.std-theme/hslogo-16.png: copyFile: does not exist (No such file or directory)

Apparently it can't find /Users/andreas/repos/temp-ghc-3/ghc-build/inplace/lib/html/Ocean.std-theme/hslogo-16.png. That file is in fact there, but it is linked to another file:

It seems to be trying to link to utils/haddock/resources/html/Ocean.std-theme/hslogo-16.png in my source tree. But the problem is that there is one too many ".." in the links. If there were one fewer ".." in the path, then it would work fine.
