rat 4.2.22-2.1 (hppa binary) in ubuntu gutsy

 RAT is a network audio tool that allows users to participate in audio
 conferences over the Internet. These can be between two participants
 directly, or between a group of participants on a common multicast group.
 No special features are required to use RAT in point-to-point mode, but to
 use the multicast conferencing facilities of RAT, a connection to the
 Mbone, or a similar multicast-capable network, is required. RAT is based on
 IETF standards, using RTP above UDP/IP as its transport protocol, and
 conforming to the RTP profile for audio and video conferences with minimal
 control.
