--------------------------+--------------------------------
 logstalgia uses libsdl and libsdl_image, but the homepage says "Logstalgia
 now uses SDL 2.0 when available, providing much better multi-monitor
 support" and "SDL 1.2 support is deprecated." MacPorts provides libsdl2
 and libsdl2_image; if logstalgia can use these instead perhaps it should.
 However, libsdl2 requires OS X 10.7 or later. If support for OS X 10.6 and
 earlier is desired, variants could be provided, with the libsdl2 variant
 being the default on 10.7 and up and the libsdl variant being the default
 on 10.6 and under.
