I did manage to build X11 and the X11-extras package. I removed the extra libs from cabal and aliased ghc to ghc -LX11. The problem seems to be with the lower case "-l" that the compiler was passed due to extra libs. The installation happened all right. Now, however, I have another problem during xmonad build; presumably these is related to the work-around I figured? ~/xmonad-0.2 <216> runhaskell Setup.lhs build Preprocessing executables for xmonad-0.2...
