I have a minimal installation of CentOS, and I wanted to then install X Windows and the GNOME desktop. I then tried the following, which failed on a dependency: $ yum -y groupinstall "X Window System" "GNOME Desktop Environment" --> Running transaction check ---> Package nautilus-sendto.i386 0:0.7-5.fc6 set to be updated --> Processing Dependency: libgaim.so.0 for package: nautilus-sendto ---> Package opensp.i386 0:1.5.2-4 set to be updated --> Finished Dependency Resolution Error: Missing Dependency: libgaim.so.0 is needed by package nautilus-sendto So GNOME appears to be missing some dependencies in the yum repository. I finally gave up and installed KDE, which installed flawlessly: $ yum -y groupinstall "X Window System" "KDE (K Desktop Environment)" I assume this is a bug with the GNOME packages (required dependency not found). Is this a CentOS issue, or an "upstream" issue? Thanks, Kenneth
