My system is OS X El Capitan (10.11.3). I'm using an installation built with a successful bootstrap from bug 564814. app-crypt/gnupg-2.0.29-r1 fails to emerge due to pulling the wrong inttypes.h: In file included from /opt/gentoo/usr/bin/../lib/clang/3.7.1/include/inttypes.h:26: /usr/include/inttypes.h:235:8: error: unknown type name 'intmax_t' extern intmax_t ^ ... There is a check in the ebuild for if CC is "clang", but that seems to fail on prefix because the real CC name is used, "x86_64-apple-darwin15-clang". I'll submit a patch for the ebuild, but the correct fix might be to make tc-getCC() return "clang". Reproducible: Always Steps to Reproduce: emerge --oneshot =app-crypt/gnupg-2.0.29-r1
