I got this recently:
```julia
julia> using FreeTypeAbstraction
INFO: Precompiling module FreeTypeAbstraction.
WARNING: Module Compat with uuid 723476325108 is missing from the cache.
This may mean module Compat does not support precompilation but is imported by a module that does.
ERROR: LoadError: Declaring __precompile__ (false) is not allowed in files that are being precompiled.

A general problem, or something created in my local setup?

unclear, but could solved by recompiling everything in .julia/lib/v0.6

Users of ScikitLearn.jl seem to get this a lot, too. Restarting Julia usually solves the issue (and if it doesn’t, restart again). Hopefully it’ll be fixed in 0.6.1
