LilyPond hangs on os x

[address@hidden]

Hey all,

I'm running LilyPond on the command line from Mac OS X and it is hanging right 
after printing the version.  I downloaded several versions (stable, unstable, 
previous unstable) and it happens with all of them.  This is a recent-ish 
development (about 5 days ago or so).

Is there a tool I could use to diagnose on what function call the hangup 
happens?

Cheers,
MS
