[Xymon] upgrade from src to Xymon 4.3.23 ?

I am running xymon compiled from source. I don't have a clear path for upgrading. I have muddled through before, but are there steps documented somewhere for UPGRADE that I am just unaware of?

May be lack of coffee, but I don't even understand the questions configure is asking today. So I have skipped running the configure and am trying to just use the previous makefile. Some note I made, makes me think I did it like that last time.

Somebody rescue me please.
