Building sys-apps/kmod with clang as compiler does not work, because the ebuild dies after a compiler version check. Afaict, there are no problems with the actual source code or build system. Reproducible: Always Steps to Reproduce: 1. emerge sys-devel/llvm[clang] 2. CPP="clang -E" CC=clang emerge -1 sys-apps/kmod Actual Results: * ERROR: sys-apps/kmod-15::gentoo failed (setup phase): * At least sys-devel/gcc >= 4.6 is required to build sys-apps/kmod. * * Call stack: * ebuild.sh, line 93: Called pkg_setup * environment, line 2946: Called die * The specific snippet of code: * version_is_at_least 4.6 $(gcc-version) || die "At least sys-devel/gcc >= 4.6 is required to build ${CATEGORY}/${PN}." Expected Results: kmod should build and install properly. Recent versions of clang report gcc-compatibility version 4.2.0. A different method for determining compiler capabilities (wrt. bug 481020) might be in order?
