Just cp /usr/portage/guarddog-1.9.15.ebuild /usr/portage/guarddog-1.9.16.ebuild It works for me --- >>> Regenerating /etc/ld.so.cache... >>> net-misc/guarddog-1.9.16 merged. >>> Recording net-misc/guarddog in "world" favorites file... --- Lintool show some warnings, but they are about the vars that are in the eclass. btw: it works with GCC-3.1 Slt!
