Because avahi does not compile avahi-client.pc unless you build it with USE="dbus" distcc silently fails to compile in support for "zeroconf", leading to distccd failing to start with flag --zeroconf. Reproducible: Always Steps to Reproduce: 1. USE="-dbus" emerge avahi distcc 2. distccd --zeroconf 3. Actual Results: $ ~ distccd --zeroconf distccd: ERROR: --zeroconf: unknown option Expected Results: $ ~ distccd --zeroconf distccd[10147] (dcc_should_be_inetd) stdin is a tty; assuming --daemon mode distccd[10147] (main) ERROR: --allow option is now mandatory; you must specify which clients are allowed to connect distccd[10147] (dcc_exit) exit: code 101; self: 0.000000 user 0.000000 sys; children: 0.000000 user 0.000000 sys Portage 2.1.6.7 (hardened/linux/x86/2008.0, gcc-4.3.3, glibc-2.8_p20080602-r3, 2.6.27-gentoo-r8 i686) ================================================================= System uname: Linux-2.6.27-gentoo-r8-i686-Mobile_Intel-R-_Pentium-R-_4_CPU_2.80GHz-with-glibc2.3.2 Timestamp of tree: Wed, 25 Mar 2009 17:30:01 +0000 distcc 3.1 i686-pc-linux-gnu [enabled] ccache version 2.4 [disabled] app-shells/bash: 3.2_p17-r1 dev-lang/python: 2.4.4-r6, 2.5.2-r7 dev-python/pycrypto: 2.0.1-r6 dev-util/ccache: 2.4-r7 sys-apps/baselayout: 1.12.11.1 sys-apps/sandbox: 1.2.18.1-r2 sys-devel/autoconf: 2.61-r1 sys-devel/automake: 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10 sys-devel/binutils: 2.18-r1 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 1.5.24 virtual/os-headers: 2.6.23-r3 ACCEPT_KEYWORDS="x86" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=pentium4 -mtune=pentium4 -O2 -pipe -fforce-addr" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/env.d /etc/gconf /etc/revdep-rebuild /etc/terminfo /etc/udev/rules.d" CXXFLAGS="-march=pentium4 -mtune=pentium4 -O2 -pipe -fforce-addr" DISTDIR="/var/portage/distfiles" FEATURES="distcc distlocks fixpackages metadata-transfer parallel-fetch protect-owned sandbox sfperms strict unmerge-orphans userfetch userpriv" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" LDFLAGS="-Wl,--as-needed -Wl,-O1 -Wl,--sort-common -Wl,--warn-once,--hash-style=gnu" MAKEOPTS="-j7 -l5" PKGDIR="/var/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/var/portage" PORTDIR_OVERLAY="/usr/local/portage/layman/xake-toolchain /usr/local/portage/mine" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X acl avahi berkdb bzip2 cli cracklib crypt cups dri gdbm git gpm hardened iconv isdnlog midi mudflap ncurses nptl nptlonly pam pcre perl pic pppd readline reflection session spl ssl sysfs tcpd urandom x86 xorg zlib" ALSA_CARDS="intel8x0" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" ELIBC="glibc" INPUT_DEVICES="evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" USERLAND="GNU" VIDEO_CARDS="sis" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, LANG, LC_ALL, LINGUAS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
