Problem to installa Virtualhere Server to Ubuntu server 12.04

Hi,
I'm new in this forum.
I have problem with installing the Virtualhere Server to Ubuntu server 12.04.
You are a guide to install software server in ubuntu server 12.04?

The command that i run are:

wget http://www.virtualhere.com/sites/default/files/usbserver/ubuntu64/vhusb…
chmod +x vhusbd64
./vhsbd64

Respond:

./vhusbd64: error while loading shared libraries: libavahi-client.so.3: cannot open shared object file: No such file or directory

If I run the vhsbd32 for x86 processor I have no answer.

This is the screen:

root@BOX0002:~# sudo ./vhusbd32
root@BOX0002:~#

Can you help me?
Thanks
