the conclusion was the same. That's why I decided to do the make directly
in ncurses as the result was immediate rather than re doing the full
compile in order to trouble shoot. I promise I will avoid that in the

Normally these should be set by the configure script I think. In the build
directory there are some config.* files, can you check whether there is any
clue in there?

This looks like the same basic problem where a tool variable is not
properly filled in.
In guess once the first problem is found, this one will be solved as well.
