Thanks. I never know which version of this supports which version 
of that. Any easy way of checking this? I mean, how can I tell 
that gdc 5.3.0-1 supports phobos 2.066?

I reckon other people run into these errors as well, and it would 
be nice if there was a way of checking whether a function is 
supported in gdc/ldc x.x.x Hmm. Sounds like a nice project with 
git, libdparse and vibe.

What about the other errors though?
