I didn't knew about :ctags of ghci.

Some time ago I've tweaked cabal to start ghci with package options
given in the .cabal file.

Perhaps it might be useful for someone:

module Main where
import Distribution.Simple
import Distribution.Simple.Configure 
import Distribution.Simple.LocalBuildInfo
import System
import System.Process
import System.Exit
import Monad

main= do
  args <- getArgs -- check args to launch ghci
  when (length args > 0) $ do
    when ((args!!0) == "ghci") $ do
	lbi <- getPersistBuildConfig
	let packageArgs = (concat.concat) [ [" -package ", showPackageId pkg] | pkg <- packageDeps lbi ]
	system("ghci " ++ packageArgs)
	exitWith ExitSuccess
  defaultMain -- fallback to defaultMain

Then you can use ./setup ghci to start ghci
It is incomplete but should work for default packages..
