graphviz 2.4 has a configuration file in /usr/lib64/graphviz/config this could be a minor problem, but graphviz tries to create a default config when that file is missing, so even when you're not running as root, it tries to open wr that file (generating an error). Of course a newly emerged graphviz misses the config and tries to create it at every run until you do it as root. to make it even worse, many ebuilds use graphviz to build the package documentation (notable example is kde*) and they fail to emerge because of access violation under sandbox. Suggested steps: 1. graphviz should emerge a default config file as well 2. graphviz should be patched to have the config file under /etc 3. graphviz should be patched to never try to autocreate the config file in a system-wide directory, maybe it could try to create it in $HOME/.graphviz Reproducible: Always Steps to Reproduce: 1. emerge graphviz-24 2. execute dot -V as normal user: pioppo@roentgen ~ $ dot -V Error: failed to open /usr/lib64/graphviz/config for write. dot version 2.4 (Sun Sep 11 15:32:18 UTC 2005) 3. after doing it as root, the error disappears: roentgen ~ # dot -V dot version 2.4 (Sun Sep 11 15:32:18 UTC 2005) roentgen ~ # logout pioppo@roentgen ~ $ dot -V dot version 2.4 (Sun Sep 11 15:32:18 UTC 2005) and we have a default config: pioppo@roentgen ~ $ cat /usr/lib64/graphviz/config libgvplugin_neato_layout.so.0 neato_layout { layout { neato 0 fdp 0 twopi 0 circo 0 } } libgvplugin_usershape_gd.so.0 usershape_gd { usershape { png-gd 0 } } libgvplugin_dot_layout.so.0 dot_layout { layout { dot 0 } } Actual Results: pioppo@roentgen ~ $ dot -V Error: failed to open /usr/lib64/graphviz/config for write. dot version 2.4 (Sun Sep 11 15:32:18 UTC 2005) ebuilds fail to emerge cause they get access denied when using dot to create documentation Portage 2.0.52-r1 (default-linux/amd64/2005.0, gcc-3.4.4, glibc-2.3.5-r1, 2.6.13-gentoo x86_64) ================================================================= System uname: 2.6.13-gentoo x86_64 AMD Athlon(tm) 64 Processor 3200+ Gentoo Base System version 1.12.0_pre8 distcc 2.18.3 x86_64-pc-linux-gnu (protocols 1 and 2) (default port 3632) [disabled] ccache version 2.4 [disabled] dev-lang/python: 2.3.5-r1, 2.4.1-r1 sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.20 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="amd64 ~amd64" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -pipe -march=k8 -funit-at-a-time -frename-registers -fweb" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/lib64/mozilla/defaults/pref /usr/share/config /var/bind /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/texmf/web2c /etc/env.d" CXXFLAGS="-O2 -pipe -march=k8 -funit-at-a-time -frename-registers -fweb" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig candy distlocks fixpackages parallel-fetch sandbox sfperms strict" GENTOO_MIRRORS="ftp://ftp-stud.fht-esslingen.de/pub/Mirrors/gentoo/ ftp://mirrors.sec.informatik.tu-darmstadt.de/gentoo/ http://ftp.uni-erlangen.de/pub/mirrors/gentoo" LANG="it_IT.UTF-8" LC_ALL="it_IT.UTF-8" LINGUAS="en it" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="amd64 3dnowex X a52 aalib acl acpi adns alsa apache2 app-crypt/gnupg:idea app-crypt/gpgme:smime arts artswrappersuid audiofile avi bash-completion berkdb bidi bigger-fonts bitmap-fonts bootsplash caps cdda cddb cdio cdparanoia cdr cluster crypt cups curl dba dev-dotnet/mono:nptl dev-util/eric:idl directfb doc dts dv dvd dvdr dvdread eds emboss encode esd faad fam fbcon ffmpeg flac foomaticdb fortran fpx freetype gcj gd gdbm gdm gif gimpprint gnome gnutls gphoto2 gpm graphviz gstreamer gtk gtk2 guile hal httpd icq imagemagick imap imlib innodb ipv6 ithreads jabber jack java jbig jpeg jpeg2k junit kde kde-base/kdeadmin:foreign-package kde-base/kdeadmin:foreign-sysvinit kde-base/kdemultimedia:cdparanoia ladcca lcms ldap libcaca libwww live lzo lzw lzw-tiff mad maildir makecheck media-sound/museseq:fluidsynth mikmod motif mozilla mp3 mpeg mysql ncurses net-misc/openssh:X509 net-misc/openssh:chroot net-misc/openssh:sftplogging net-misc/openssh:skey net-www/apache:threads net-www/mozilla-firefox:xprint net-www/mozilla:mozp3p net-www/mozilla:mozsvg network nls nptl nptlonly nsl nvidia ogg oggvorbis openexr opengl oss pam pcre pdflib perl png python qt quicktime readline rrdtool rtc samba sasl sdl slang speex spell ssl stream svg sys-devel/libperl:threads tcltk tcpd tetex tga theora threads tiff truetype truetype-fonts type1-fonts unicode usb userlocales utf8 vcd vim-with-x vorbis wmf xine xml xml2 xmms xpm xprint xv xvid xvmc zeo zlib linguas_en linguas_it userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LDFLAGS
