Description of problem: When the package is rebuilt in an everything install buildroot it picks up a dependency on libpng12.so.0 This indicates that there might be a missing build requirement (libpng-devel) to get full functionality. If this is not intented, linking with libpng12 should probably disabled with a configure parameter Version-Release number of selected component (if applicable): gnome-applet-vm-0.1.2-1 (The packages also looses a dependency on libxml2.so.2, but I've not looked at it yet)
Hold on, maybe this requirement can be added to gtk2-devel and a simple rebuilt is all all that is needed. See bug #232013
build requirement has been added to gtk2-devel, a simple rebuild should fix this issue.
