i've installed several themes (nuvola for exemple) and they dont appear in kcontrol. Even after X restarted. files are here (/usr/share/icons/nuvola) and KDEDIRS seems ok (/usr/). That's the same for widgets themes (.so). This is an amd64. This explains the pb for the .so (hidden in lib64, on another amd64 gentoo i've fixed that by hand copying the libs to where kde goes to find them). But i'm stucked with the icons pbs...
i've got the pb on another computer, ~x86 : Portage 2.1_pre7-r3 (default-linux/x86/2005.1, gcc-3.4.6, glibc-2.4-r1, 2.6.15-gentoo-r5 i686) ================================================================= System uname: 2.6.15-gentoo-r5 i686 Pentium III (Coppermine) Gentoo Base System version 1.12.0_pre16 dev-lang/python: 2.3.5-r2, 2.4.2-r1 sys-apps/sandbox: 1.2.17 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-r2 sys-devel/binutils: 2.16.1-r2 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r3 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -mcpu=i686 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/kde/3/share/config /usr/share/X11/xkb /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/eselect/compiler /etc/gconf /etc/revdep-rebuild /etc/terminfo /etc/texmf/web2c /etc/env.d" CXXFLAGS="-O2 -mcpu=i686 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks metadata-transfer sandbox sfperms strict" GENTOO_MIRRORS="ftp://mir.zyrianes.net/gentoo/ http://ftp.snt.utwente.nl/pub/os/linux/gentoo ftp://ftp.wh2.tu-dresden.de/pub/mirrors/gentoo" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="x86 X alsa apm arts avi berkdb bitmap-fonts cli crypt cups dri eds emboss encode foomaticdb fortran gdbm gif gnome gpm gstreamer gtk gtk2 imlib ipv6 isdnlog jpeg kde libg++ libwww mad mikmod motif mp3 mpeg ncurses nls nptl nptlonly ogg oggvorbis opengl oss pam pcre pdflib perl png pppd python qt quicktime readline reflection sdl server session speex spell spl ssl tcpd theora truetype truetype-fonts type1-fonts vorbis xml2 xmms xorg xv zlib elibc_glibc kernel_linux userland_GNU video_cards_ati" Unset: ASFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, LINGUAS, MAKEOPTS, PORTDIR_OVERLAY
