I tried to unmerge kde-3.0.5a, but failed to do so because kde-base/kde-3.0.5a was protected. So I went forward to unmerge the ebuilds themselves, but the command ebuild --debug kdeaddons-3.0.5a/kdeaddons-3.0.5a.ebuild unmerge resulted in !!! Please specify a valid command. I looked at /usr/sbin/ebuild and /usr/lib/python2.2/site-packages/portage.py and noticed that in the portage module the unmerge command is missing from the list of valid commands in the first check performed by the doebuild function. Adding "unmerge" to the list of valid commands solved my problem. Reproducible: Always Steps to Reproduce: 1. ebuild --debug kdeaddons-3.0.5a/kdeaddons-3.0.5a.ebuild unmerge Actual Results: Ebuild returned with !!! Please specify a valid command. Expected Results: Unmerge the ebuild. Note that this happened after emerge sync ; emerge portage ; emerge sync No outdated config files were present Portage 2.0.47-r8 (default-x86-1.4, gcc-3.2.2, glibc-2.3.2_pre1-r0) ================================================================= System uname: 2.4.20-gentoo-r1 i686 AMD Athlon(tm) processor GENTOO_MIRRORS="http://gentoo.oregonstate.edu/ http://distro.ibiblio.org/pub/Linux/distributions/gentoo" CONFIG_PROTECT="/etc /var/qmail/control /usr/kde/2/share/config /usr/X11R6/lib/X11/xkb /usr/kde/3.1/share/config /usr/kde/3/share/config /usr/share/config" CONFIG_PROTECT_MASK="/etc/gconf /etc/env.d" PORTDIR="/usr/portage" DISTDIR="/usr/portage/distfiles" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR_OVERLAY="" USE="x86 oss 3dnow apm crypt cups encode gif libg++ libwww mikmod mpeg ncurses pdflib quicktime spell gdbm berkdb slang svga java guile gpm tcpd pam ssl esd motif X gtk gnome kde qt alsa -postgres -arts cdr python perl opengl sdl jpeg png truetype xml xml2 dvd readline ruby avi fbcon mmx nls oggvorbis pda gphoto2 imlib mozilla xv xmms zlib" COMPILER="gcc3" CHOST="i686-pc-linux-gnu" CFLAGS="-march=athlon -O3 -pipe" CXXFLAGS="-march=athlon -O3 -pipe" ACCEPT_KEYWORDS="x86 ~x86" MAKEOPTS="-j2" AUTOCLEAN="yes" SYNC="rsync://rsync.gentoo.org/gentoo-portage" FEATURES="sandbox ccache"
