[Haskell-cafe] how to get ghci to load compiled modules in 7.8?

I recently upgraded to 7.8.2 and I have a silly question. How do you get ghci to load compiled modules? When I try this: % cat >T.hs module T where x :: Int x = 42 % ghc -c -dynamic-too T.hs % s T.dyn_hi T.dyn_o T.hi T.hs T.o % ghci GHCi, version 7.8.2: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done. Loading package integer-gmp ... linking ... done. Loading package base ... linking ... done. Loading package filepath-1.3.0.2 ... linking ... done. Prelude> :l T [1 of 1] Compiling T ( T.hs, interpreted ) Ok, modules loaded: T. *T> It still loads the file interpreted, even though there is a .dyn_o present. What am I doing wrong? This is on x86-64 OS X.
