For no reason other than I could, I tried running strace on the
lilypond run. I have little idea what I'm doing or what I'm looking
at, but I have been able to find clues to problem programs in the past
this way.
For the record, the exact command I ran was:
strace -e trace=file -o straceLilypond -t lilypond score.ly
I won't put the whole output here (unless someone really wants it),
but I noticed a couple of things that may or may not be useful. First,
there were many calls to files that don't exist on my system:

are typical examples.
Second, here is the context of what I'm presuming is the
'Preprocessing graphical objects...' slowdown:

In my untrained opinion I have absolutely no idea if there's anything
wrong here. If somebody else has a clue, I'd love to hear your wisdom!
