-prof and -threaded work fine together, but you do need the profiling
libraries installed.  You don't need special -prof/-threaded libraries:
only the RTS changes when you specify -threaded.

Try -prof and +RTS -xc, you might be pleasantly surprised (or
unpleasantly surprised: it doesn't *always* work).
