Has anyone managed to get PHP 5.4 working with unit?

[clegginabox]

Yes I know it's an unsupported and a very old version. It's a legacy application currently running on EC2 instances, I'm wanting to replace it with containers running in fargate and then upgrade the PHP version as far as possible (much easier to do with containers)

I've got an M2 mac and I've been trying all day to get something working in Docker.

I guess my question pretty much mirrors this - https://stackoverflow.com/q/78587877

According to this comment - PHP 5.4 is supported, so i'm hoping someone has done it before and can point me in the right direction - #858 (comment)

So far I can compile and install PHP 5.4 and create a module with unit
