Afflib installation issue

Hello,

I am trying to install Autopsy on an M1 Macbook Pro.

I’m using this guide: https://slo-sleuth.github.io/tools/InstallingAutopsyOnMacOS.html

For the most part, everything is going smoothly. However, at the ./configure step, the only required element of support that I am missing is afflib. Is anyone else having this issue?
