I will take care of that for sunrise, but I would like to ask the author to create a versioning system for his builds.
This is now in the sunrise overlay. You can find it soon at: http://gentoo-sunrise.org/svn/reviewed/app-portage/kelogviewer There are more frontends for GTK (bug #136496) and curses/text mode (bug #150733)
Is in Portage as app-portage/kelogviewer
