The aim is to build foo (of M2) as a library, then to make Main under the package foo, and with profiling. (snip) runhaskell Setup.hs build Preprocessing library foo-1.0... Building foo-1.0...

Lemmih's reply is correct. Don't use ghc-options, cabal doesn't know that it should now be looking for the .p_o file rather than the .o file unless you tell to by configuring w/ profiling enabled. peace, isaac
