Package: apt
Version: 0.5.0
Severity: grave

The upgrade to APT 0.5 totally broke dependency calculation.  apt-get
upgrade gives the following (totally erroneous) error:

Sorry, but the following packages have unmet dependencies:
  apache-common: Depends: libc6 (>= 2.2.1) but 2.2.2-1 is to be installed
  binstats: Depends: debianutils (>= 1.13.1) but 1.15 is to be installed
  wvdial: Depends: libc6 (>= 2.1.94) but 2.2.2-1 is to be installed

Note that the package versions required are all less than those
installed.  dpkg --compare-versions correctly compares these versions
correctly, as in this output:

[sam@samth ~]$ dpkg --compare-versions 2.2.1 "<=" 2.2.2-1 && echo 1    

Installation of debs manually with dpkg also works properly, with none
of these complaints.  It is merely apt that has difficulty.  

It seems, although I'm very much not sure about this, that the bug
relates to comparing versions where the lesser one has more components
than the greater (2.2.1-1 vs 2.2.2, etc).

I would have liked to have seen your configuration file..

But in any event, it appears to be an odd side effect of mis
configuration, however that is possible.

I'm sure someone else will discover it if there is indeed a real issue
