Haskell - why getSymbolicLinkTarget is not in scope?

I get this error:

/home/jacek/hasktemp/src/Main.hs:40:31: error:
    Variable not in scope: getSymbolicLinkTarget :: [Char] -> IO a0
   |
40 |                 symlTarget <- getSymbolicLinkTarget emacsdf
   |                               ^^^^^^^^^^^^^^^^^^^^^

when I try to find the target of a symlink.

The gist of my code is here: https://gist.github.com/bigos/9da53d11c53fe642bfe90444be76cb7c

and my imports have

import System.Directory

The documentation http://hackage.haskell.org/package/directory-1.3.3.1/docs/System-Directory.html#g:6 has getSymbolicLinkTarget, yet I get the error. what I am doing wrong?

getSymbolicLinkTarget's documentation says, in part:

Since: directory-1.3.1.0

You probably have an older version of the directory package than that. Consider adding a constraint like directory>=1.3.1 to your cabal file.
