this did not work. I have nothing on my screen or in any log.
php -i sais I used the correct php.ini

This was REALLY strange. I don't know if this is expected behaviour, but 
using valgrind, the server is up and running.

I created a full output, ...

/usr/local/httpd-test/bin/httpd -k start)

... which you can find here:
