If gtk were not installed, I would install it, of course. So two problems: 1. there is no "gtk2" or "gtk3" package as all the gtkX relates stuff have additional parts to their names. So, which package precisely is it that the installer is looking for? $ rpm -q -a|grep ^gtk gtk2-metatheme-adwaita-3.2.1-2.1.2.noarch gtk3-immodule-amharic-3.2.1-2.5.1.x86_64 gtk2-engines-32bit-2.20.2-7.1.2.x86_64 gtk-sharp2-gapi-2.12.10-32.1.2.x86_64 gtk2-tools-32bit-2.24.7-2.5.1.x86_64 gtk-sharp-beans-2.14.1-10.1.2.x86_64 gtk-vnc-lang-0.4.3-6.1.2.noarch gtk2-immodule-inuktitut-2.24.7-2.5.1.x86_64 gtk3-immodule-vietnamese-3.2.1-2.5.1.x86_64 gtk2-data-2.24.7-2.5.1.noarch gtk2-tools-2.24.7-2.5.1.x86_64 gtk-sharp2-doc-2.12.10-32.1.2.x86_64 gtk2-immodule-thai-2.24.7-2.5.1.x86_64 gtk3-data-3.2.1-2.5.1.noarch gtk-sharp2-complete-2.12.10-32.1.2.x86_64 gtk3-immodule-inuktitut-3.2.1-2.5.1.x86_64 gtk3-theming-engine-adwaita-3.2.1-2.1.2.x86_64 gtk-sharp2-2.12.10-32.1.2.x86_64 gtk2-immodule-amharic-2.24.7-2.5.1.x86_64 gtk3-metatheme-adwaita-3.2.1-2.1.2.noarch gtk3-immodule-thai-3.2.1-2.5.1.x86_64 gtk2-engines-2.20.2-7.1.2.x86_64 gtksourceview-sharp2-0.12-107.1.1.noarch gtk2-branding-openSUSE-12.1-4.1.1.noarch gtk-vnc2-lang-0.4.3-6.1.2.noarch gtk2-devel-2.24.7-2.5.1.x86_64 gtk2-immodule-vietnamese-2.24.7-2.5.1.x86_64 gtksourceview2-lang-2.10.5-3.1.2.noarch gtk3-tools-3.2.1-2.5.1.x86_64 gtk3-branding-openSUSE-12.1-5.1.1.noarch 2. How is the installer testing for gtk? I'd guess it is not querying the RPM manager. Since I don't know what it is looking for, I don't know how to ensure it finds what it ought to have found in the first place. I will continue with the install since a similar thread seems to indicate that I won't be destroying my current install with this one: http://software.intel.com/en-us/forums/showthread.php?t=102403
