investigating low accuracy of spamassissin I got this error while doing sa-learn --spam -D : DB_file module not installed, cannot use Bayes I emerged DB_File and everything is ok btw I have -berkdb among my USE flags, and consequently DB_File was not insalled with Spamassassin maybe DB_File has to be a dependency no matter if berkdb USE flag is set to on or off Reproducible: Always Steps to Reproduce: # emerge info Portage 2.0.51-r15 (default-linux/x86/2004.3, gcc-3.3.5, glibc-2.3.4.20040808-r1, 2.6.10-gentoo-r6 i686) ================================================================= System uname: 2.6.10-gentoo-r6 i686 Unknown CPU Typ Gentoo Base System version 1.4.16 Python: dev-lang/python-2.3.4-r1 [2.3.4 (#1, Feb 7 2005, 23:22:39)] dev-lang/python: 2.3.4-r1 sys-devel/autoconf: 2.59-r6, 2.13 sys-devel/automake: 1.8.5-r3, 1.5, 1.4_p6, 1.6.3, 1.7.9, 1.9.4 sys-devel/binutils: 2.15.92.0.2-r1 sys-devel/libtool: 1.4.3-r4, 1.5.10-r4 virtual/os-headers: 2.6.8.1-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-O2 -march=i686 -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3/share/config /usr/lib/X11/xkb /usr/lib/mozilla/defaults/pref /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -march=i686 -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks sandbox sfperms" GENTOO_MIRRORS="http://ftp.uni-erlangen.de/pub/mirrors/gentoo/ http://gentoo.oregonstate.edu/ http://www.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/home/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="x86 3dnow X aalib alsa apache2 apm avi bitmap-fonts bonobo cdr crypt cups directfb divx4linux dvd eds encode esd evo f77 fam fbcon flac font-server foomaticdb fortran gdbm gif gimpprint gnome gpm gstreamer gtk gtk2 gtkhtml imagemagick imlib innodb ipv6 irmc java jpeg ldap libwww mad mmx motif mpeg mysql ncurses nls nntp nozaptel odbc oggvorbis opengl oss pam pdflib perl png ppds python quicktime samba scanner sdl sqlite sse ssl svga tcpd tiff truetype truetype-fonts type1-fonts usb xinerama xml xml2 xmms xv zlib" Unset: ASFLAGS, CBUILD, CTARGET, LANG, LC_ALL, LDFLAGS
This was done on purpose -- if you don't want the Berkeley DB (dependency of DB_File), you won't get any Berekely database support. The spamassassin ebuild prints out a big fat info about this after installation. You have two choices: 1. Don't USE=-berkdb (or add berkdb for spamassassin to your package.use). 2. Use an alternative Bayes storage like a MySQL database.
