 When I bmake configure for graphics/MesaLib and do:
 
 grep -R gelf .
 
 I still get:
 
 ./work/mesa-11.2.2/src/gallium/state_trackers/clover/llvm/invocation.cpp:#include
 <gelf.h>
 
 Is it correct that for graphics/MesaLib and that alone, there is the
 fix in its options.mk of:
 
 .include "../../devel/libelf/buildlink3.mk"
 CPPFLAGS+=        -I${BUILDLINK_PREFIX.libelf}/include/libelf
 
 I just don't see what the problem is with altering libelf's
 buildlink3.mk to actually reflect what its pkgconf *.pc file also
 claims to be the correct include path.
 
 It astounds me how hard the work is to NOT make things work out of the
 box.  Can't use the pkgconf *.pc whose very purpose is to tell other
 packages where to find stuff.  Can't alter the buildlink3.mk to
 reflect what the *.pc file says.
