synaptic warning, multiple versions of packages

[ArmenD]

I am also getting the following for several packages when i start synaptic...
how do i resolve this issue?
can I simply delete the old version of a package & how?

here is the warning I am getting...

 There are multiple versions of "shadow-utils" in your system.

This package won't be cleanly updated, unless you leave
only one version. To leave multiple versions installed,
you may remove that warning by setting the following
option in your configuration file:

RPM::Allow-Duplicated { "^shadow-utils$"; };

To disable these warnings completely set:

RPM::Allow-Duplicated-Warning "false";

rpm --help

shows me, that

rpm -e

will erase (uninstall) a package.
