That has to be the reason I didn't understand it :)

Unfortunately, no, because I still have no clue what path has to be  
passed (I did not investigate any further because the autoconf  
version conflict (bug 1220, pointed out by me22) prevented me from  
configuring the paths at all. I got it working with some manual  
hacking though.

Anyways, it didn't even come to my mind that this is a standard  
feature of autoconf. Maybe a hint in that direction and/or a short  
example would be helpful.
