Thanks crazycaveman, that worked for me.
Now how do I upgrade the libtorrent? I have version 0.15.10.
I have a Raspberry Pi unit with Raspbian installed.

I still don't understand how to update the libtorrent.
Where are the instructions?

Also, I'm unable to update Deluge.
I get the following error right at the beginning of the process: "-bash: deb: command not found"
Please help. Thank you!

I have version 1.3.3 installed on Raspberry pi with Raspbian Wheezy.
It crashes a lot.
How do I update it to the latest version?
