New description:

 On my unbuntu OS, cabal install catagory-extras put the files as shown
 here:
 {{{
 [ 99 of 100] Compiling Control.Morphism.Exo ( src/Control/Morphism/Exo.hs,
 dist/build/Control/Morphism/Exo.o )

 whereas with manual install, they're put as shown here:

 When I compile with ghc, ghc cannot find the /root/.cabal files.  If the
 -i
 flag is used, the files are found; however, another error occurs:
 {{{

 differs from name found in the interface file category-

Comment:

 So what you're doing is a per-user install as root. Either run `cabal
 install catagory-extras` as your ordinary user account or if you really
 want to do a global install then do:
 {{{
 sudo cabal install catagory-extras --global
 }}}
 or
 {{{
 cabal install catagory-extras --global --root-cmd=sudo
 }}}
 The latter will do just the install part as root.

 Perhaps this is suprising and we should try and detect if we are root and
 if so then do a global install by default. Unfortunately detecting if we
 are running as root is not simple and not portable (and just because we
 are uid=0 does not mean we have permissions under modern unix security
 mechanims and likewise we can have permissions to do global installs
 without being a root user).
