Yes, it's entirely possible masterblaster. That's why I include most of the gems. The problem is that the program uses... well I think it's 17 libraries all said and done. About 10 of which have to be compiled for the target platform. The ones that I don't include are so common that I don't consider it any risk at all.Ruby is a very popular language. It's much bigger than Bitcoin. Some of the top 10 websites in the world are built on the Ruby on Rails framework. There's no risk of profiling through the libraries not included -- that's my opinion, and we've established that I'm more cautious than necessary.As for Ruby 2.0... I haven't even tried 2.0 yet, so I'm not even sure it would work even if you could install the dependencies properly. A higher version number does not always mean "better in every way." The Linux kernel is on 3.8 I think now, but they still backport security fixes for the 2.6 series. Frequently people don't care about features, they want stability and security -- Ruby 2.0 is a feature release focusing on features and speed. 1.8 and 1.9 are safer.
