Do you mean install it manually as shown in the aforementioned How_to_install_a_Cabal_package?

No, I mean go to http://hackage.haskell.org and download the .tar.gz file directly (http://hackage.haskell.org/cgi-bin/hackage-scripts/package/category-extras). Unzip/untar that package. I haven't looked at it, but there is probably a "src" directory. Put your example file in there and load it in ghci. Your source file should then use the source available in that directory tree rather than the category-extras install which seems broken. This works because the GHC will look at the import "Control.Functor.Fix" and use that to look for "Control/Functor/Fix.hs" from the current directory.

Tried that but: <--- cut here --- GHCi, version 6.8.2: http://www.haskell.org/ghc/ :? for help Loading package base ... linking ... done.

Yes, thanks.
