How can I get C-c C-l to first run cpp on a .hsc file and then load the .hs file? I checked out the network package from darcs and then did: Start ghci, C-c C-z, then: Prelude> :set -cpp And then pressed load, C-c C-l: Prelude> :load "/Users/tibell/src/haskell/network-bytestring/Network/Socket.hsc" <command line>: Could not find module `/Users/tibell/src/haskell/network-bytestring/Network/Socket.hsc': Use -v to see a list of the files searched for. Failed, modules loaded: none.
