Compiling RTG on EL9

Hello, I am just curious with the demise of EL7 if anyone else is working on trying to compile RTG for EL9. If you don't know what RTG is it's just an old SNMP poller/graph plotter that some networks have found useful in the past. If you've had any luck getting this recompiled in EL9 please let me know. I've kept it going from EL5-EL7 but I'm running into some wacky issues this time around. Off-list is definitely encouraged since I'm not sure anyone even knows what this is anymore. Thanks, -Drew
