In exim-4.82.1 dsearch lookup type was available, due to the line sed -i "s:# LOOKUP_DSEARCH=yes:LOOKUP_DSEARCH=yes:" Makefile in the src_configure() function of the ebuild. However, exim-4.83_rc1 is lacking this lookup type and consequently failing to deliver mail for config files using it. Adding the above line manually to the 4.83_rc1 ebuild in src_configure() makes the lookup type available again. Reproducible: Always Steps to Reproduce: 1. Update exim to 4.83_rc1 2. Restart exim (with config that utilizes dsearch). Actual Results: Exim bails out of mail delivery with error "unknown lookup type dsearch". Expected Results: dsearch lookup should be available, so that delivery succeeds. # emerge --info Portage 2.2.10 (default/linux/amd64/13.0, gcc-4.8.2, glibc-2.19, 3.14.4-gentoo-thor x86_64) [7/9872] ================================================================= System uname: Linux-3.14.4-gentoo-thor-x86_64-AMD_Athlon-tm-_64_Processor_3700+-with-gentoo-2.2 KiB Mem: 2050016 total, 32368 free KiB Swap: 2096112 total, 1729896 free Timestamp of tree: Thu, 29 May 2014 13:45:01 +0000 ld GNU ld (GNU Binutils) 2.24 app-shells/bash: 4.2_p47 dev-lang/python: 2.7.6-r1, 3.3.5, 3.4.0 dev-util/cmake: 2.8.12.2-r1 dev-util/pkgconfig: 0.28-r1 sys-apps/baselayout: 2.2 sys-apps/openrc: 0.12.4 sys-apps/sandbox: 2.6-r1 sys-devel/autoconf: 2.69 sys-devel/automake: 1.14.1 sys-devel/binutils: 2.24-r2 sys-devel/gcc: 4.8.2 sys-devel/gcc-config: 1.8 sys-devel/libtool: 2.4.2-r1 sys-devel/make: 4.0-r1 sys-kernel/linux-headers: 3.14 (virtual/os-headers) sys-libs/glibc: 2.19 Repositories: gentoo gentoo-haskell x-portage ACCEPT_KEYWORDS="amd64 ~amd64" ACCEPT_LICENSE="* -@EULA" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=native -O2 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/gnupg/qualified.txt" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/php/apache2-php5.5/ext-active/ /etc/php/cgi-php5.5/ext-active/ /etc/php/cli -php5.5/ext-active/ /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo" CXXFLAGS="-march=native -O2 -pipe" DISTDIR="/usr/portage/distfiles" EMERGE_DEFAULT_OPTS="--jobs=1 --load-average=2" FCFLAGS="-O2 -pipe" FEATURES="assume-digests binpkg-logs candy clean-logs config-protect-if-modified distlocks ebuild-locks fakeroot fixlafiles merge-sync news parallel-fetch preserve-libs protect-owned sandbox sfperms splitdebug strict unknown-features-warn unmerge-backup unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync" FFLAGS="-O2 -pipe" GENTOO_MIRRORS="ftp://sunsite.informatik.rwth-aachen.de/pub/Linux/gentoo ftp://ftp.tu-clausthal.de/pub/linux/gentoo/" LANG="C" LDFLAGS="-Wl,-O1 -Wl,--as-needed" MAKEOPTS="-j2 -l2" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --omit-dir-times --compress --force --whole-file --delete --stats --human-readable --timeout=180 --exclude=/distfiles --ex clude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/var/lib/layman/haskell /usr/local/portage" SYNC="rsync://rsync.de.gentoo.org/gentoo-portage" USE="acl amd64 berkdb bzip2 cli cracklib crypt cxx dri fortran gdbm iconv ipv6 mmx modules multilib ncurses nls nptl openmp pam pcre readline session sse sse2 ssl tcpd unicode vim-syntax zlib zsh-completion" ABI_X86="64" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident us b-audio via82xx via82xx-modem ymfpci" APACHE2_MODULES="authn_core authz_core socache_shmcb unixd actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm a uthz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include inf o log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" CALLIGRA_FEATURES="kexi words flow plan sheets stage tables k rita karbon braindump author" CAMERAS="ptp2" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin gar mintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ublox ubx" INPUT_DEVICES="keyboard mouse evdev" KERNEL ="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LIBREOFFICE_EXTENSIONS="presenter-console presenter-minimizer" LINGUAS="en de" OFFICE_IMPLEMENTATI ON="libreoffice" PHP_TARGETS="php5-5" PYTHON_SINGLE_TARGET="python2_7" PYTHON_TARGETS="python2_7 python3_3" RUBY_TARGETS="ruby21" USERLAND="GNU" VIDEO_CARDS="fbdev glint intel mach64 mga nouv eau nv r128 radeon savage sis tdfx trident vesa via vmware dummy v4l" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq stea l rawnat logmark ipmark dhcpmac delude chaos account" USE_PYTHON="2.7 3.3" Unset: CPPFLAGS, CTARGET, INSTALL_MASK, LC_ALL, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
Thanks! I've added this back. Since I only committed this ebuild this afternoon, I fixed it without revbump.
