When emerging hostap-drivers on my system, I got some access violations slapped in my face by emerge. It took my some time to figure out the cause of the problem: Sandboxing. My idea is this: Let emerge state the actual cause of access violations where possible. In my case for example it might have said: 'Building files with FEUTURES=sandbox may cause this.' Or another option is to let certain packages, like hostap, that need or want to build outside the sandbox, display a notice of this fact. IMHO this feature will save quite a lot of Gentoo newbies some headaches. Reproducible: Always Steps to Reproduce: Portage 2.0.50-r8 (default-x86-2004.0, gcc-3.3.2, glibc-2.3.2-r9, 2.4.26-mod1) ================================================================= System uname: 2.4.26-mod1 i686 Mobile Intel(R) Pentium(R) 4 - M CPU 2.00GHz Gentoo Base System version 1.4.16 Autoconf: sys-devel/autoconf-2.59-r3 Automake: sys-devel/automake-1.8.3 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-O2 -mcpu=i686 -march=i686 -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" COMPILER="gcc3" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3/share/config /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -mcpu=i686 -march=i686 -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs ccache sandbox" GENTOO_MIRRORS="http://ftp.easynet.nl/mirror/gentoo/ http://gentoo.oregonstate.edu http://www.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="X apm arts avi berkdb crypt cups encode foomaticdb gdbm gif gnome gpm gtk gtk2 imlib jpeg kde libg++ libwww mad mikmod motif mpeg ncurses nls oggvorbis opengl oss pam pdflib perl png python qt quicktime readline sdl slang spell ssl svga tcpd truetype x86 xml2 xmms xv zlib"
later versions of portage are much more verbose about this.
