problems with 6-2-branch

Dear GHC team,

It occurs problematic for me to build correct  cvs ghc-6-2-brach. 
 
Now, I have built cvs  ghc-6-2-branch  first in 
                                /home/mechvel/ghc/cvs/6-2-branch/inst 
,
then, after  cd fptools
             make clean

rebuild  ghc-6-2-branch  by   /home/mechvel/ghc/cvs/6-2-branch/inst/bin 
,
installed it to   /home/mechvel/ghc/cvs/6-2-branch/inst2/bin 
,
erased all  ghc  except  /home/mechvel/ghc/cvs/6-2-branch/inst2/bin 
,
tested:  > which ghc
           /home/mechvel/ghc/cvs/6-2-branch/inst2/bin/ghc
         > which ghci
           /home/mechvel/ghc/cvs/6-2-branch/inst2/bin/ghci
         >
,
`made' DoCon by the Makefile containing 
                    ghc = /home/mechvel/ghc/cvs/6-2-branch/inst2/bin/ghc
                    ...

`made' the test  T_  by     > ghc $pcpdocon --make T_ 
,

run the test by             > ghci $pcpdocon T_ 
and got
   ...
   [True,ghc-6.2.1: internal error: scavenge:
      unimplemented/strange closure type 64 @ 0x404033f0
    Please report this as a bug to glasgow-haskell-bugs@xxxxxxxxxxx,

Now there is no doubt that in this latter test  ghc and ghci are
of the same place.
 
And it looks like you cannot reproduce the effect.

Maybe, this is system specific?
Have you tried this on  Debian linux  or  RedHat linux?

Maybe, you can provide me with correct  ghc-6-2-branch-binary ?

One is for  Debian Linux .. 2.4.25 #2 Mon Apr 26 .. 2004 i686 unknown, 
            libc-2.2.5.so
            (once  ghc-6.2.1-binary  was installled there).

Another -- for  RedHat linux 9,  libc-2.3.2.so.

----------
Another question:
how to build  ghc-6-2-branch  from source  
without using pre-installed GHC 
(as to Alex and Happy, OK, I think, let them be pre-installed)
and to install it into my user chosen directory
?
I tried `make' from various places, and it says
"you have not run ./configure".
And "./configure" searches for  ghc  installed, for Happy.

I am sorry, can you tell me precisely what to do?

With kind regards,
