Found the problem. The libclang package is looking for 
/usr/lib/llvm-3.9/lib/libclang.so. For some reason, Ubuntu has 
libclang.so.1. Creating a symlink in that directory to 
libclang.so is a solution.

Do you have the development package (probably something like 
libclang-3.9-dev) installed ? Usually they are the ones 
containing the correct symlink (see 
https://forum.dlang.org/thread/ea9432f8d37a563bc4920d0bb8748ae7ab23dfd4.camel winder.org.uk)

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.

I don't think it's confusing, you will also need to install the 
development package if you are coding something in C. It's the 
same, except for the language being D instead of C. As D is 
advertised as a systems programming language, this doesn't seem 
confusing (to me, at least).

If a dub package uses a system library though, it can be hinted 
at by the `systemDependencies` key in `dub.json`/`dub.sdl`. The 
problem is, I don't think many packages actually use it and I 
agree that since it's too easy to overlook it, you're often left 
to figure everything out. It's not something you're likely to 
find out unless you are already looking for it.
