The configure of your package checks for flex, even though your package might not contain .l files that flex uses to generate parsers. Your ebuild does not list a dependency on flex as per http://tinderbox.dev.gentoo.org/misc/dindex/sys-devel/flex . Either disable the flex test during configure to avoid false positive, or add the dependency upon flex if it's needed by your package. Thanks in advance, Diego
