Hey Ivan,

Thanks for your response.

The first one is that you didn't run `oasis setup` after you made the

I tried cleaning up all the generated files. Same error unfortunately

I am using oasis 0.4.7 and ocaml-4.03.0, but I don't appear to be using
flambda. I tried passing in -config and it said that flambda was false at
least, but I admit, I'm not especially familiar with it, so if there's some
other way I should be checking for this please let me know. Hopefully,
they're compatible sans flambda?
