No need to send patch upstream, latest version uses cmake and revamped build system. *kadu-0.6.0.2-r1 (04 Feb 2009) 04 Feb 2009; Robert Buchholz <rbu@gentoo.org> metadata.xml, +files/kadu-0.6.0.2-kill-strip.patch, -kadu-0.6.0.1.ebuild, -kadu-0.6.0.2.ebuild, +kadu-0.6.0.2-r1.ebuild: Do allow building against internal libgadu, remove USE flag.
