Failure to build metapp.0.4.4

[benbellick]

Hi, thanks for this package (and the million other awesome packages you've made).

I seem to encounter a sporadic error both locally and on CI/CD with a project that uses metapp. Really it uses override which depends on metapp.

System Info:

• OCaml Version: 4.12.1
• OS: MacOS 14.0
• Chip: M2 Max

[ERROR] The compilation of metapp.0.4.4 failed at "dune build -p metapp -j 11
