Interesting, someone has actually reported this in the past but Ive never
been able to reproduce it. The two most likely explanations are either
opening up a UDP listener port is forbidden by some security/firewall
policy on your system (many OS's have started enabling these by default),
or something else is using the port you are trying to create the OSC server

Im not sure how to test the former on Linux, but you can see if anything is
listening on that port using netstat -lntu. If any of the ports on the
local addresses (the part after : ) matches the OSC port you are trying to
use, then that would be your problem- you can just use a different OSC port
in ChucK in that case.
