While testing mp3kult for stable marking I ran into this. It seems to need arts due to using an old buildsystem (info provided by flameeyes) [ebuild N ] media-sound/mp3kult-0.7-r3 -arts -debug -xinerama emerge info ______________________________________ Portage 2.0.54 (default-linux/x86/2006.0, gcc-3.4.5, glibc-2.3.5-r3, 2.6.16.9 i686) ================================================================= System uname: 2.6.16.9 i686 AMD Athlon(tm) 64 Processor 3200+ Gentoo Base System version 1.6.14 dev-lang/python: 2.4.2 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-r1 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=k8 -O2 -fomit-frame-pointer -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3/share/config /usr/lib/X11/xkb /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/eselect/compiler /etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-march=k8 -O2 -fomit-frame-pointer -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig collision-protect distlocks sandbox sfperms strict" GENTOO_MIRRORS="ftp://ftp.snt.utwente.nl/pub/os/linux/gentoo/" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.nl.gentoo.org/gentoo-portage" USE="x86 3dnow 3dnowext X aac acpi alsa apache2 avi bitmap-fonts bzip2 cairo cdb cdparanoia cli crypt ctype cups dri dvd dvdread eds encode esd exif expat fam ffmpeg firefox foomaticdb ftp gd gdbm gif gstreamer gtk gtk2 iconv icu idn isdnlog jpeg jpeg2k kde kdeenablefinal libwww lm_sensors mad mmx mmxext mozsvg mp3 mpeg mplayer msn mysql ncurses network nls nomotif nptl nptlonly nsplugin ogg opengl pcre pdflib php png posix ppds pppd qt quicktime rdesktop readline reflection rtc session sharedmem sockets spl sse sse2 ssl svg tcpd tetex tiff truetype truetype-fonts type1-fonts udev unicode userlocales vorbis win32codecs xml xml2 xorg xpm xv zlib video_cards_radeon input_devices_keyboard input_devices_mouse userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, LINGUAS, MAKEOPTS, PORTDIR_OVERLAY
Forgot to mention the actual error: checking for mcopidl... not found configure: error: The important program mcopidl was not found! Please check whether you installed KDE correctly.
Fixed by requiring arts for good.
