making with profiling, 6.4.1, cabal-1.1.3

I need help on making for profiling,
and cannot decide whether the question is on GHC or on Cabal.

I have  ghc-6.4.1,  and  Cabal-1.1.3-September-12  
installed in my user directory, under Debian Linux,
and need to make a project for profiling.

        ghci -package Cabal 
 Loading package base-1.0 ... linking ... done.
 Loading package Cabal-1.1.3 ... linking ... done.

I start with a contrived example project of  M1.hs, M2.hs, Main.hs:

module M1 where  m1 = True
module M2 where  import M1;  m2 = m1 && m1

Main.hs:  import M2l;        main = putStr $ shows m2 "\n"

For this,          ghc --make -prof -auto-all Main

works as needed -- without packages.
Now, try to make a package for profiling:

  name:            foo
  version:         1.0
  build-depends:   base, haskell98, data
  exposed-modules: M2
  other-modules:   M1
  ghc-options:     -prof -auto-all -hisuf p_hi -osuf p_o

The aim is to build  foo  (of M2)  as a library, then to make Main 
under the package  foo,  and with profiling.

Then,  runhaskell Setup configure --ghc --prefix=$source/inst
       runhaskell Setup build

produces a report

scico:~/t> make build

runhaskell Setup.hs build

The directory   ~/t/dist/build   contains at this moment

  M1.p_hi  M1.p_o  M2.p_hi  M2.p_o  Main.p_hi  Main.p_o

, and indeed, no  M2.o  file.

If I remove  -hisuf p_hi -osuf p_o

(by the way, why should the user think of these wise suffixes,
maybe,  -prof  should be sufficient?
then it reports  ... 
                 /usr/bin/ld: cannot find -lHSfoo-1.0_p
                 collect2: ld returned 1 exit status

What I am missing, please?
Thank you in advance for the help.
