I think it should be better under RDEPEND to use: RDEPEND="${DEPEND} ... || ( app-arch/unrar app-arch/rar ) instead of the current RDEPEND="${DEPEND} ... app-arch/unrar I'm actually using the 'unrar' binary from the app-arch/rar package because of a bug in the binary provided by app-arch/unrar (the bug seems related with the '-av-' option used by amavis-new to decompress .rar files)
In CVS, thanks for suggestion!
