Error compiling (missing JNA?)

Running the docker build, and erroring due to missing JNA?

This will severely impact performance! To resolve this, use separate rules and declare dependencies instead of using symbolic links.

It seems that buck has changed a little bit over the las months. The current code actually fails with the latest buck as deps are not longer supported in genrules. Also, some tests fail for me even with those changes.

I'd try an older version of buck, let's says a version submitted a couple of days earlier than the original weslang commiy.
