Here's a hack I sometimes use to that effect: create a script
'fakeghc.sh' with the following contents (or a similiar program):

,----
| #!/bin/sh
| 
| case "$1" in
|   --interactive)
|      echo "$*"
|      exit
|     ;;
| esac
| 
| exec ghc $*
`----

and then invoke cabal like so

| cabal repl --with-ghc=./fakeghci.sh

HTH,
