boxbackup 0.11.1 is the current stable release. (For whatever reason, upstream has listed it on their wiki but not on the main boxbackup.org page.) I have successfully installed boxbackup 0.11.1 on AMD 64, both USE=client-only and full installs, using the ebuild attached to bug 299411. Could we please update portage? Thanks
