That helped.
$ aptitude remove ghc
did not remove or install any packages, but now ghc --version says 6.10.2
on the other hand, ghc 6.8.2 is still on the system
dpkg -l says
ghc6 6.8.2dfsg1-1 GHC - the Glasgow Haskell
Compilation system
ghc6-doc 6.8.2dfsg1-1 Documentation for the Glasgow
Haskell Compilation system
ghc6-libsrc 6.6-3 Library Sources of GHC, the

/usr/local/bin/ghci-6.10.2
/usr/local/bin/ghc-pkg -> ghc-pkg-6.10.2
/usr/local/bin/ghc-pkg-6.10.2
so /usr/local/bin shadows the /usr/bin directory? I am not sure if I'm
going to run into trouble with this installation, so I decided to
completely uninstall the old ghc6. It removed some other packages, too:
g++-4.1{u} ghc6 ghc6-prof{a} haskell-utils{u} libgmp3-dev{u}
libgmpxx4ldbl{u} libncurses5-dev{u} libreadline5-dev{u}
libstdc++6-4.1-dev{u}
After that, there was no ghc anymore except the 6.10.2 - as desired. But
a hello-world-compilation failed because of missing lgmp. So I installed
libgmp3-dev and libgmpxx4ldbl
Now it seems to work again, but I expect to run in trouble again. I'll
keep you up-to-date.
Thanks,
Daniel

What does happen if you uninstall ghc-6.8.2 by using dpkg/apt-get? IIRC
ghc is completely linked statically (haskel libs) so your 6.10.2 does
not depend on 6.8.2.
Cheers,

Thanks for the answer.
I upgraded from Debian Etch to Lenny, and this upgraded ghc to version
6.8.2. Then I tried again to install ghc-6.10.2 and it worked without
problems.
But now I have 2 versions, and by default ghc-6.8 is called. Is there a
simple way to make ghc-6.10 the default ghc? Do I have to change the
symlinks by hand?
Thanks,
Daniel

IIRC, this happens if you have binutils 2.17. Upgrading should fix it.
Thanks
