I didn't know that meson 0.29 is available on their xenial-based 
VMs but i was adviced yesterday to use xenial because it has 
python 3.5 which is good enough for meson. This is what i did, 
everywhere([1],[2],...), so everything is fine now.

By the way meson 0.29 is probably not capable of building D. This 
looks like a very old release.
