Yeah, I didn't need the symlink on a different machine with 
Ubuntu 18.04. After some digging around, I found that I had 
libclang1-3.9, libclang-dev, and libclang-common-3.9-dev 
installed. libclang1-3.9 installs libclang.so.1. The one I was 
missing was libclang-3.9-dev.

It's confusing and I think this could be handled better by the 
distro. But this is also one of the reasons I'm not a fan of dub. 
The user is left to sort through these dependencies themselves, 
and that means it's really not suitable for packages that link to 
C code (which is most of what I do). One of the main selling 
points of D is its C interoperability, but a lot of new users 
would walk away rather than trying to figure this out, concluding 
that D is buggy.
