Find attached an ebuild for symbackup, a GTK front-end to rdiff-backup. It depends on net-misc/rdiff-backup and x11-libs/gtk+.
Created attachment 28793 [details] net-misc/symbackup-0.0.3.ebuild (New Package)
I must admit: I am leaning towards not including this package in the Portage tree. The package seems to be unchanged for 2 years and doesn't even have a proper homepage, which leads me to believe the developer wrote it as a test of his/her programming skills. There is no reference to symbackup on the jpilot.org front page and the only reference to it on Google are all Gentoo-related (e.g., it seems no one anywhere actually uses this). Repoen if I'm in error, or this package is touched.
