sys-fs/e2fsprogs-1.41 depends on sys-libs/e2fsprogs-libs-1.41.2 which RDEPENDs on !sys-libs/com_err and !sys-libs/ss. heimdal-0.7.2-r3 depends on sys-libs/com_err and sys-libs/ss which both RDEPEND on !sys-fs/e2fsprogs. Reproducible: Always Steps to Reproduce: 1. Have machine with existing Heimdal installation 2. Update to current portage tree 3. emerge --update has circular blocking caused by sys-libs/ss, sys-libs/com_err and sys-libs/e2fsprogs-libs Expected Results: No circular blocking caused by unmasking latest e2fsprogs $ emerge --info Portage 2.1.4.4 (default/linux/amd64/2008.0/no-multilib, gcc-4.1.2, glibc-2.6.1-r0, 2.6.21-xen x86_64) ================================================================= System uname: 2.6.21-xen x86_64 AMD Opteron(tm) Processor 242 Timestamp of tree: Wed, 29 Oct 2008 08:17:01 +0000 ccache version 2.4 [enabled] app-shells/bash: 3.2_p33 dev-java/java-config: 1.3.7, 2.1.6 dev-lang/python: 2.4.4-r13, 2.5.2-r5 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: 2.13, 2.61-r2 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.1 sys-devel/binutils: 2.18-r3 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 1.5.26 virtual/os-headers: 2.6.17-r2 ACCEPT_KEYWORDS="amd64" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=opteron -O3 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /var/bind" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/terminfo /etc/texmf/web2c /etc/udev/rules.d" CXXFLAGS="-march=opteron -O3 -pipe" DISTDIR="/misc/distfiles" EMERGE_DEFAULT_OPTS="--with-bdeps y" FEATURES="ccache distlocks metadata-transfer noautoaccts parallel-fetch sandbox sfperms strict unmerge-orphans userfetch" GENTOO_MIRRORS="http://gentoo.virginmedia.com http://www.mirrorservice.org/sites/www.ibiblio.org/gentoo http://gentoo.oregonstate.edu http://www.ibiblio.org/pub/Linux/distributions/gentoo" LDFLAGS="-Wl,-O1" MAKEOPTS="-j4" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_EXTRA_OPTS="--progress --stats" 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="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="3dnow X Xaw3d aac aalib acl acpi aim alsa amd64 apache2 arts audiofile avi bash-completion berkdb bluetooth bonobo bzip2 caps cdb cdr cjk cli cpdflib cracklib crypt cups curl dba dbm dbus dga directfb divx4linux doc dri dts dvb dvd dvdr encode esd exif expat fam fbcon fftw flac flash foomaticdb fortran ftp gd gdbm gif gnome gphoto2 gpm gtk gtk2 gtkhtml hal iconv icq imagemagick imap imlib innodb ipv6 irmc isdnlog jabber jadetex java jbig joystick jpeg jpeg2k kde kerberos lcms ldap libedit libwww lirc lm_sensors mad maildir mailwrapper mhash midi mime ming mmx mng mp3 mpeg msn mudflap mysql ncurses nls nptl nptlonly offensive ogg openal opengl openmp oscar pam pcre pdf pdflib perl php png postgres ppds pppd python qt3 quicktime readline reflection samba sasl sdl seamonkey session slp snmp spell spl sse sse2 ssl svg sysfs tcl tcltk tcpd tetex theora tiff tk truetype unicode usb v4l v4l2 videos vorbis wmf xattr xine xinerama xml xml2 xorg xpm xsl xv xvid yahoo zlib" ALSA_CARDS="emu10k1 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 auth_digest authn_anon authn_dbd 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 dbd deflate dir disk_cache env expires ext_filter file_cache filter headers ident imagemap include info log_config logio mem_cache mime mime_magic negotiation proxy proxy_ajp proxy_balancer proxy_connect proxy_http rewrite setenvif so speling status unique_id userdir usertrack vhost_alias" CAMERAS="canon" ELIBC="glibc" INPUT_DEVICES="keyboard mouse vmmouse joystick" KERNEL="linux" LCD_DEVICES="mtxorb xosd text ncurses" LIRC_DEVICES="hauppauge" USERLAND="GNU" VIDEO_CARDS="fbdev i810 nv nvidia mga vesa r128 radeon vmware vga" Unset: CPPFLAGS, CTARGET, FFLAGS, INSTALL_MASK, LANG, LC_ALL, LINGUAS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS
Do you really use heimdal ? While this may be a valid bug, heimdal isn't supported very good in Gentoo, so heimdal 1.2.1 is not stable yet, but it's been in the tree for quite awhile. It introduced so many changes, that a massive revdep-rebuild was required.
