I am in Ubuntu 12.04 (precise) 64bit and downloaded the btsync executable from http://labs.bittorrent.com/experiments/sync/ but running it doesn't seem to have any effect. Double-clicking the executable does nothing, and running ./btsync in the terminal also exits immediately without any output.

Has anyone successfully ran this under Ubuntu, and if so, is there any special configuration changes that need to be made to make it work?
