Older Mac Compatibility Issues (Compiling C++ dependancies on installation)

I figured Id start this by defending my use of an older device for DV-specific projects. I think most people who are going to work capturing old footage like this will need Firewire compatible hardware. Ive found a sweet spot on MacOS11 with a firewire card. Im sure there is a mile-long cable that you could construct that would plug into new mac thunderbolt or usb-c connectors, but I dont have such a cable... or a new computer lol

I've not been able to get the installation through homebrew to work. Some of the dependencies (im finding mpv, vapoursynth in particular) throw the error:

when compiling the vapoursynth dependancy. Other C++ programs seem to have issues compiling too. Wondering if anyone had a fix for this. For reference, my system has:
