Pironman5 and DietPi v9.12 fails wiith sysv_ipc

Hi,
I’m using DietPi v9.12 and found that when building Pironman5 software it fails in two places.
I’m following the pironman5 instructions from Set Up on Raspberry Pi/Ubuntu/Kali/Homebridge OS — SunFounder Pironman 5 documentation

The first error is “Install from source: error” and then unable to build sysv_ipc.

A simple fix is to install gcc..

apt install gcc

I later noticed that DietPi was no longer on the supported OS.
It was listed on the older pironman documentation.

We are sorry, but DietPi is not compatible with pironman5 software.
We recommend that you choose a compatible system.
The compatible link you provided is a tutorial for the pironman4 chassis, which is not applicable to pironman5.
