Build failure on macOS with Dune master #1633
Description
We are seeing this in odoc's CI, in the macOS row:
<><> Processing actions <><><><><><><><><><><><><><><><><><><><><><><><><><> 🐫
[ERROR] The compilation of dune failed at "/Users/travis/.opam/4.07.0/.opam-switch/build/dune.1.6.2/./boot.exe --release -j 1".

The version number is misleading. Dune 1.6.2 release installs fine. We are actually using Dune master at that point in CI.
