problems after upgrading libc6

[lead@gmx.de]

hi debians

i´ve got a problem after upgrading hamm-libc to 2.0.7u-4:

i installed libc6_2.0.7u-4 manually which is required by staroffice 5
but after upgrading my apt (0.1.6) couldn´t install anything further
it says:

Checking system integrity...dependency error
You might want to run apt-get -f install' to correct these.
Sorry, but the following packages are broken - this means they have unmet
dependencies:
  apt: Depends:libc6
  
and apt-get -f install want´s to downgrade libc6 back to hamm´s version
and with this so5 won´t run

i´ve tried to install so5 on my notebook which is already upgraded to slink
-- and there are no problems except memory problems (so5 is overkill on a 
little slight notebook especially with 16mb ram ,-)

do i have to install slink´s version of apt (0.1.7) or did i miss any library?
or - which isn´t common in the moment - upgrade my pc to slink, too?

any hint is welcome;)

until next mail ;)             . ___ ---___              .--.
