[gentoo-user] can I unmerge these duplicate pkgs ?

[R'twick Niceorgaw]

Hi I just ran qpkg --dup -v and got the following list.   Is it safe to unmerge all older versions leaving just the latest version installed or will it give me any problems ?   regards R'twick   # qpkg --dups -v app-text/docbook-sgml-dtd-3.0-r1 app-text/docbook-sgml-dtd-3.1-r1 app-text/docbook-sgml-dtd-4.1-r1 app-text/docbook-sgml-dtd-4.0-r1 dev-libs/glib-1.2.10-r5 dev-libs/glib-2.2.1 sys-libs/db-1.85-r1 sys-libs/db-3.2.9-r2 x11-libs/gtk+-2.2.1 x11-libs/gtk+-1.2.10-r10
