Yes, I had similar messages. BTW, are you directly connected to the
Raspberry Pi or over network? I tried the build on a remote Debian 10
shell machine too. Mged doesn't run there either but the errors are
about OpenGL which makes sense, OpenGL doesn't really work over the
network. I thought maybe that's the problem with Raspberry Pi too but
haven't tried.

So if you're not directly connected, it's worth reporting this as a
bug. I may try that too later.
