I did a new test, again completely from scratch.
I built ncurses and readline, installed them system wide (normal make install
without a --prefix).
Then i editing Modules/Setup.dist to include readline and adding the correct
paths
to the include and libs files. configure now finds the readline library.
However, ncurses and readline still fail to be built.
I had a look at the output of make.
This is the error for ncurses:
