[CM] linux-port of OpenMusic

Greetings,

Made a simple patch, renamed it, OM crashed with this report :

**

Ctrl-C gets me out of the loop, and the patch is renamed correctly - and 
works - when I restart. It's a simple calculator for a harmonic series, 
copied from this video :

The patch doesn't appear to cause any problems. Maybe LW doesn't get 
along with Xfce on Ubuntu 12.04 ?

Please advise if you need more information, I'm happy to help debug, 
though I'll need some pointers. It's been a while since I last worked 
with Common Lisp.

Best,
