      My bad, in fact we do.

Could you try with the attached patch? It shows the failing filename in

Ah, sorry, that line was truncated. I posted the output here:

That line should be
+ghc-iserv.bin: internal loadArchive: GNU-variant filename offset not found while reading filename from `/home/omer/haskell/ghc/libraries/ghc-prim/dist-install/build/libHSghc-prim-0.5.0.0.a'

Did this line get truncated? It might help to have the rest of it.
