I’m not sure why my perl installation got broken, but I was not able to fix it. I ended up with a fresh Raspbian installation. Now everything works fine egain.
if you have mapped to keyboard, you will have to either change it so one is mapped to enter, or just use a small wireless keyboard for configuring etc.
thx for the help, finally got it compiled, but it mostly just crashes back to retroarch 10 seconds into startup on the games I wanted it for. ahh, well, that's why it's called experimental.

OK. I'll wait. I was intending to read the current code to understand how stuff works and contribute in some way. But if it is being rewriten, I think it's better to wait a little longer. Hope to see a little more commented code... :-)
