profiling in Cabal in 6.4.1-aug-1

Dear GHC developers,

I have `made'  ghc-6.4.1.20050801  

by its binary, on Linux Debian, and tested on DoCon and Dumatel 
application.
The first `make' crashed (I do not know, maybe, indeed, a hardware
fail). The second (by new) succeeded.

It looks all right -- except `making' with profiling.

Without profiling, it `makes' and installs.
For profiling,  dm.cabal  adds 
                          -prof -auto-all -hisuf p_hi -osuf p_o
to its options.
The commands
    runhaskell Setup configure --ghc --prefix=$dmSource/inst 
    runhaskell Setup build 

seem to work all right. Then,   runhaskell Setup install --user 
reports

  Installing: /home/mechvel/dm/1.03/dm/source/inst/lib/dumatel-1.3 & 
              /home/mechvel/dm/1.03/dm/source/inst/bin dumatel-1.3...
  Error: Could not find module: Dumatel with any suffix: ["hi"]

And the directory  $dmSource/dist/build/  contains
                                          Dumatel.p_hi, Dumatel.p_o
among its files.
