[Haskell-cafe] How to use Plugins package?

I'm newbie and I've got a problem.

I'm trying to get example programs from plugins-auto [1] or hotswap [2] to work.
I think question on stackoverflow [3] somewhat related to my problem.

They are compiled well, but in runtime I get either
or Prelude.undefined
or internal error: PAP object entered!

I use GHC 7.4.1. x86_64 Ubuntu

I've read "Plugging Haskell In" and would like to make some fun with
plugins, but alas...

Maybe -dynamic flag is what I seek? Or maybe I need to know something else?
Maybe I needn't use Plugins package like in gitit?

Please, could you explain how to compile plugins in haskell correctly?
Where should I start?
