Interesting -- I didn't know that.

I appear to have made an inadvertent mistake in my original post; sorry
about that.  I'm using MacTeX 2012, not TeXLive 2012.  I don't know if this
has any significance or not, though.  (I'm also not entirely clear on the
relationship between MacTeX and TeXLive.  Are they basically the same thing
on MacOS?)

I mention this now only because I went looking to see if the fonts are at
the location given above on my system, and they're not.  This is probably a
good thing, because I downloaded them myself from SIL's website and put
them in ~/Library/Fonts.  Since they're not also in /usr/local, I don't
have to worry about which copy XeTeX is using, which is nice.

I'll try to look at the other responses in this thread when I have a little
bit more time tomorrow -- thanks to all who've made suggestions!
