Petri Damsten has a tellico-svn ebuild setup for Gentoo, which you can find at his “portage overlay” (not sure exactly what that means…) at http://susku.pyhaselka.fi/svn/portage/kde-misc/tellico-svn/. With it, installing the current SVN trunk for Tellico is as simple as: emerge tellico-svn. I would caution you that the trunk code can be a bit a bumpy. Things get broken, and partially implemented, so be careful and always backup your data files.
