I managed to get hashed-storage installed by patching Setup.hs replacing:

import System( system, exitWith )

with:

import System.Process( system )
import System.Exit( exitWith )

and adding process>=1.0.1.1 to the build-depends.


I also needed to replace:

import System( system )
import System.Process ( ProcessHandle,
                        runInteractiveProcess, waitForProcess,
                        getProcessExitCode )

with:

import System.Process ( ProcessHandle,
                        runInteractiveProcess, waitForProcess,
                        getProcessExitCode, system )

in darcs' Distribution/ShellHarness.hs to get it to compile.


I don't know whether these changes would let these packages continue to build 
against older versions of GHC/base but if anyone wants them I can create 
proper darcs patches if they're useful.
