I had a similar problem building on one machine and had to work through the missing packages to get a (nearly) complete build. Building on a fresh install of Ubuntu Xenial worked much better, without the problems of missing/mismatched packages.

In both cases, I ended up with 7 deb files which installed and worked fine. The final perarch deb build failed, but doesn't seem to affect my system in any way that I've found so far. If anyone knows whether that's a problem, I'd like to know... The failure was a missing stdarg.h from the kernel.h include while building the perarch deb.
