Kali linux is the next version of backtrack in a completely new form. Tor is not installed by default in kali linux. However can be installed easily right from its own repositories.
[email protected]:~# apt-get install tor vidalia
Run the above command and tor along with vidalia should be installed.
Start the tor service with the following command
[email protected]:~# service tor start [ ok ] Starting tor daemon...done.
Verify tor status with the following command
[email protected]:~# service tor status [ ok ] tor is running.
Or just use Vidalia from the menu, "Applications > Internet > Vidalia".
