A big list of libraries one has to install is kind of intimidating, yeah. But them's the breaks.

What seems particularly offensive to me is that it declares that it specifically requires GCC 4.9. I'm really not OK pinning your brand new impressive world changing open source cloud technology to a compiler release series that's 3.5 years old. It looks either staid, or uncaring, or otherwise dull to have slipped to far behind the times, and it's intimidating to think the codebase is complex enough C or C++ that it really matters a whole lot.
