I actually have a question regarding build as well. I haven't been able to build 3.1 branch from source on Ubuntu 16.04 x86_64. I hit this error:

I'm actually able to build the 3.1 branch on s390x so I'm wondering if I'm missing some pre-reqs or setting? Any clues would be much appreciated!

Wonder if that might help you. Yes it works! Thanks! -- Ian Partridge
