I’m running into a weird error trying to install the latest version of foundationdb (FoundationDB-6.3.12) on the latest version of macos (11.3)

The shasum matches what is listed on the downloads website (`93833b6...`) Does anyone know whats going on here? Or how to debug the install script?

Ah thankyou - I evidently searched using the wrong part of the error message.
