I finally figured out where they got the ideas for the first such game.
(me) Trying to install a program:
(it): Please install libxml++-1.0 or 2.6 where pkg-config and scons can find it
(10 minutes later)
(me) finds libxml++
(it): gtkmm24 >= 2.6.0 is needed by libxml++2-2.12.0-1.1.fc4.nr.i386
(me)
(10 minutes later)
(me) finds gtkmm24
(it): libcairo.so.2 is needed by gtkmm24-2.8.1-1.1.fc4.nr.i386
(it): libpangocairo-1.0.so.0 is needed by gtkmm24-2.8.1-1.1.fc4.nr.i386
(me):
(15 minutes later, after finding both of those):
(it): glitz is needed by cairo-1.0.2-1.1.fc4.nr.i386
(it): libpixman >= 0.1.5 is needed by cairo-1.0.2-1.1.fc4.nr.i386
