What is the procedure for profiling under GHC 7.10.1 and cabal 1.23?

Question

What is the recommended procedure for profiling under GHC 7.10.1 and cabal 1.23? The profiling-related error and warning messages from GHC and cabal-install are very inconsistent.

1. Try to run an executable with profiling, and you are told:

   $ prediction-interactive +RTS -p
   
   prediction-interactive: the flag -p requires the program to be built with -prof
   

2. Put -prof in your cabal file, and you are told:

   $ cabal build
   
   Warning: 'ghc-options: -prof' is not necessary and will lead to problems when
   used on a library. Use the configure flag --enable-library-profiling and/or
   --enable-executable-profiling.
   

3. Follow that advice (and remove -prof from the cabal file), and you are told:

   $ cabal configure --enable-executable-profiling
   
   Resolving dependencies...
   Configuring creatur-wains-prediction-1.0...
   Warning: The flag --enable-executable-profiling is deprecated. Please use
   --enable-profiling instead.
   

4. Follow that advice, and you are told:

   $ cabal configure --enable-profiling
   
   Resolving dependencies...
   Configuring creatur-wains-prediction-1.0...
   
   $ cabal build
   
   . . .
   Installing executable(s) in
   /home/eamybut/nosync/sandboxes/prediction-wains/bin
   Installed creatur-wains-prediction-1.0
   
   $ prediction-interactive +RTS -p
   
   prediction-interactive: the flag -p requires the program to be built with -prof
   

Facepalm!

EDIT: Added cabal build in step 4.
