Thanks for the response, and my apologies for not reading the documentation. In my defense,... this documentation more regularly than not only contains the "general" instructions "execute ./configure followed by make and make install" and stuff. Hence I refrained from reading it.
I should make a habit of - if the first attempt fails - first read more documentation instead of thinking: "Now that is something these developers didn't think about".
