I downloaded the zip and gave it a try (Ubuntu amd64 on a machine with a 
core i7 CPU and 12Gb RAM; Lilypond 2.13.49). First attempt ran for about 
five seconds, producing dozens and dozens of midi error msgs like so:

programming error: Impossible or ambiguous (de)crescendo in MIDI.
continuing, cross fingers
MIDI output to `dance.midi'...
programming error: Going back in MIDI time.
continuing, cross fingers

and then stopped with a message saying "Compilation successfully 
completed", though only a midi file was produced, no PDF.

I commented out the \midi { } in the score block and ran another 
compilation. When I checked after a few minutes, System Monitor showed 
that Lilypond was using 1.1Gb of RAM, which goes a long way to 
explaining why your machine with 768Mb RAM can't build it within any 
reasonable timeframe, as continual swapping to disk would be making the 
build very slow.

The score took 705 seconds (eleven and three quarter minutes) to 
complete building and produce a PDF. So I'd say the solution is more RAM.
