getting libc6 updated after uml-utilities screwup

[ldoolitt@recycle.lbl.gov]

Friends -

I can't find my way to fix my half-upgraded libc6 on amd64 sid,
caused by bug #362058.  I have apt-get pointed to
  deb http://ftp.us.debian.org/debian/ unstable main
so I now have libc6{,-dev}_2.3.6-7 and uml-utilities_20060323-3
ready to install.  But even with the --force-yes switch, no
combination of the three packages will install properly.

Three examples:

# apt-get --force-yes install uml-utilities                        
Reading package lists... Done
Building dependency tree... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies.
  libc6-dev: Depends: libc6 (= 2.3.6-7) but 2.3.6-4 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

# apt-get --force-yes install uml-utilities libc6 libc6-dev

libc6-dev is already the newest version.
Suggested packages:
  glibc-doc user-mode-linux
The following packages will be upgraded:
  libc6 uml-utilities
2 upgraded, 0 newly installed, 0 to remove and 182 not upgraded.
2 not fully installed or removed.

One more hint:
# ls -l /usr/lib64
lrwxrwxrwx 1 root root 3 2006-03-31 08:29 /usr/lib64 -> lib

Help!  I'm sure the fix is simple, I just don't know what it is.
