I make a new ebuild from www-apache/mod_macro-1.1.6 and add ~amd64 to KEYWORDS. Successfuly compiled with sys-devel/gcc-4.1.1 and used by net-www/apache-2.0.58-r2. I use without problems. emerge --info Portage 2.1-r2 (hardened/amd64, gcc-4.1.1, glibc-2.3.6-r4, 2.6.16-hardened-r10 x86_64) ================================================================= System uname: 2.6.16-hardened-r10 x86_64 AMD Athlon(tm) 64 Processor 3500+ Gentoo Base System version 1.12.4 app-admin/eselect-compiler: [Not Present] dev-lang/python: 2.4.3-r1 dev-python/pycrypto: 2.0.1-r5 dev-util/ccache: [Not Present] dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.17 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2 sys-devel/binutils: 2.16.1-r3 sys-devel/gcc-config: 1.3.13-r3 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="amd64" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=k8 -O2 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /var/bind" CONFIG_PROTECT_MASK="/etc/env.d /etc/gconf /etc/revdep-rebuild /etc/terminfo" CXXFLAGS="-march=k8 -O2 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks metadata-transfer multilib sfperms strict" GENTOO_MIRRORS="http://gentoo.inf.elte.hu/ " LINGUAS="en hu" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude='/distfiles' --exclude='/local' --exclude='/packages'" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="acl amd64 apache2 berkdb chroot crypt dlloader hardened justify nls pam pcre pic readline ssl tcpd unicode userlocales xml xorg zlib elibc_glibc input_devices_mouse input_devices_keyboard kernel_linux linguas_en linguas_hu userland_GNU" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, PORTAGE_RSYNC_EXTRA_OPTS gcc -v Using built-in specs.
