I've been using yum from the command line and decided to see how well the GUI of "smart" works. So I installed it via yum and all dependencies were met. But when I try to start it, this happens: [root@neuron ~]# smart --gui error: Interface 'gtk' not available However [root@neuron ~]# rpm -q --requires smart /usr/bin/python libc.so.6 libc.so.6(GLIBC_2.0) libc.so.6(GLIBC_2.1) libc.so.6(GLIBC_2.1.3) libc.so.6(GLIBC_2.3) libc.so.6(GLIBC_2.3.4) libc.so.6(GLIBC_2.4) libpthread.so.0 python(abi) = 2.4 python-abi = 2.4 rpm-python >= 4.4 rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 smart-config No gkt is mentioned. What "gtk" package am I missing? Here's what's on my system: [root@neuron ~]# rpm -qa | fgrep -i gtk gtkspell-2.0.11-1.2.1 usermode-gtk-1.85-2.2 pygtk2-2.8.6-0.fc5.1 gtk+-1.2.10-50 gnome-python2-gtkhtml2-2.14.0-1 libgtk-java-2.8.6-2.fc5 gtk2-engines-2.7.4-3 gtk2-2.8.20-1 gtkhtml3-3.10.3-1.fc5.1 gtkhtml2-2.6.3-1.2.1 gtk2-devel-2.8.20-1 gtk-doc-1.6-1.fc5.1 pygtk2-libglade-2.8.6-0.fc5.1 authconfig-gtk-5.2.3-1 pygtk2-devel-2.8.6-0.fc5.1 Dean
