Problem to load libcompiler.so plugin on NetBSD 10.1

[Beesdeckar]

Watch the source code for CB used by Beesdeckar and ensure that it is the latest as the other thread

Be sure that I am working with latest branch from svn. First time I thought that 20.03 is something new.
Some new info: see link in wxWidgets forum, I repeat problem with help of their sample "exec". But it reproduces only from time to time.
