Trouble Compiling Zandronum, Twister OS, Raspberry Pi 400

[Breeder]

Hello, this post is much the same as my recent GzDOOM Compiling post. I am on a Raspberry Pi 4 running Debian based Twister OS, and am using the Wiki guide on how to compile Zandronum on Linux, but I get so far then end up with this error:
