This is a new requirement so I think it should be documented somewhere.

How to fix

Ubuntu:
apt-get install -y libclang-dev

   Compiling failure v0.1.8
error: failed to run custom build command for `fil-blst v0.1.1`

From a side channel:

One option if you don't want this extra dep would be to check in bindgen.rs and not call bindgen in build.rs

I'd prefer if we just keep that dep.
