I see.  In a package rename scenario, we don't have a package removal
procedure then.  If we had:

OpenCSW: New packages, CSWfoo depending on CSWlibbar

User: pkgutil -y -i CSWfoo
CSWlibbar gets installed automatically.

OpenCSW: We changed our mind, CSWlibbar is deprecated, CSWlibbaz has
some of these files now

User: pkgutil -u CSWfoo
CSWlibbaz gets installed automatically

Now the user has both CSWlibbar and CSWlibbaz.  You can imagine
scenario, where the presence of CSWlibbar could lead to problems,
especially if we produce more packages under the assumption that
CSWlibbar is gone.

Do you guys think we should have a mechanism that make sure that
CSWlibbar gets removed?
