Sounds like the hook should not change the working directory.

eg instead of:

install pkg_descr lbi copy_dest =
  excursion "templates" $ do
  let dataDir = mkDataDir pkg_descr lbi copy_dest
  createDirectoryIfMissing True dataDir
  sequence [ copyFile f (dataDir ++ '/':f) | (f,_) <- all_templates ]

it should stay in the same dir and just prefix "templates/":

install pkg_descr lbi copy_dest = do
  let dataDir = mkDataDir pkg_descr lbi copy_dest
  createDirectoryIfMissing True dataDir
  sequence [ copyFile ("templates" </> f) (dataDir </> f)
           | (f,_) <- all_templates ]
