Nothing to do with Jam, it's your Linux/X11 installation that seems to have the problem. libXxf86vm seems to be missing (XFree86 Video Mode Extension Library). Perhaps you need to install it (libxxf86vm-dev), or perhaps it's not in the right directory, or it isn't sym-linked correctly (see <http://ubuntuforums.org/showthread.php?p=1962696> Note 2), or the right path is not set for the linker to find X11 libraries ?
