[icecast] Placing Icecast in a chroot jail

Hi, 

(Sorry for the long email)

As a bit of a learning exercise, I'm trying to place the icecast daemon
in a chroot jail.  I've been mostly sucessful: I can get icecast to
serve the default stream from its jail, however I can't get multiple
streams to work.

I think the problem is that icecast can't resolve addresses in the jail,
however I do have an etc/hosts file and resolv.conf inside the jail. 
When I start icecast outside of the jail the following is dumped to the
log file:

Inside the jail, I get this:

Is there some file I'm missing that icecast needs? Is there something
wrong with my configuration?  Any help would be appreciated.

Thanks,
