Check out your system -- /usr/lib/X11 should be a symlink to 
/usr/X11R6/lib.  And, eventually we'll see X11R7 :-)

Hmm.  That's not how /etc/ld.so.conf works.  Is augmenting bad in some 
way?  All it does is avoid missing libraries installed in the standard

Given that PKG_CONFIG_PATH currently points at the pkgconfig directory 
itself, I'd say locating the /lib/ section and replacing it with /share/ 
borders on mystic behaviour.

Yeah, that makes sense.

However /etc/ld.so.conf is managed should give us a strong clue as to a 
reasonable answer.
