After digging a little deeper into the mailing list archives, I've
concluded that I need to fiddle with ImageMagick and GraphicsMagick on
my system and try recompiling xastir. I have both IM and GM installed,
but based on what I've read (and your comments above), I should prefer
GM over IM.

I'm at the office now, but hopefully I'll have some time this evening to
mess with it. I'll report my findings if there's anything worth reporting.

Thanks.
