In Ubuntu, the network does not seem to be available

What steps will reproduce the problem?
1. Install the new acme-sac debian package,
2. Open acme and use README
3. right click on http://cm.bell-labs.com/sys/doc/acme.html

What is the expected output? What do you see instead?

I expect the link to open in acme. Instead I get an error in
the console 
[$Math] Broken: "sys: fp: exception status=0000 pc=0x80acc7d"

Right clicking on manual pages works just fine.

If I try to execute Local mount -A tcp!plan9.bell-labs.com!wiki /mnt/wiki

I get the error,

mount: can't dial tcp!plan9.bell-labs.com!wiki: Address family not supported by 
protocol (/net/tcp/clone)
119 "Mount":fail:dial failed

And if I try to execute ip/ping 8.8.8.8 I get
ip/ping: can't dial icmp!8.8.8.8!1: network unavailable icmp

What version of the product are you using? On what operating system?
Using the acme-sac featured on the front page. Using ubuntu 12.10

Sorry, wrong project. I apologize. Can't close this issue now because google 
refuses to let me edit.
