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:

If it's any help, the directory list for src/Control/Category is:

You might have more luck finding out what's going on by emailing
Haskell-Cafe directly, too.
Yes, thanks.
