Hi, nice plugin!
I'm with Ubuntu 12.10 64bit here and seems like everything is fine and the installation occurs.
Just one thing: when I search for something, the list is populated with many occurences of the same package (even with the same repo address). I'm not a "bower guy", so I don't know if it's a bower thing or a sublime-bower thing.
Thanks for letting me know @tarciozemel, thats great news!
I've noticed a couple of double ups myself, I'll close this issue and open a new one to track any duplicates.
