Naturally, you'll get 126.96.36.199, since it has the highest version number!
Either rename your modified version to 2.4 (or similar), specify the
exact version in your *application's* cabal file, or use
"ghc-pkg hide" to hide version 188.8.131.52 from view.
If I haven't seen further, it is by standing in the footprints of giants
