As it does for me on Intel Linux. 800x600 "blue":

Now, it could be:
1) the way that Mach, shared libraries, and the
BSD style kproc interfaces all slightly mismatch,
2) the overloaded Aqua windowing system,
3) the way that Qt/Mac and/or MythTV were badly ported
(I blame the hacker who did mythfrontend, myself :-)
but either way, that ain't gonna run on an iPhone.
Maybe in ten years, when they have a gig of RAM and
a terabyte of flash, but not currently.
