Experiments that analyze dependencies in RedHat Linux and
RpmFind.net show disturbing conflicts and overlaps between software
packages that result in installing multiple differing versions of
dynamic libraries. The final state of a system containing conflicting
packages depends upon the order in which packages are installed, as
well as user input during the installation process. This leads to
system states that may or may not have been tested, lowering
confidence that the resulting software configuration will function
properly. We describe the details of the problem, potential effects,
and potential solutions involving improving the practice of building
