the GNUstep gui.

BUT
$locate jpeglib.h
/opt/local/include/jpeglib.h

$locate png.h
/opt/local/include/libpng14/png.h
/opt/local/include/png.h

$locate tiffio.h
/opt/local/include/tiffio.h

I tried adding $export LD_LIBRARY_PATH=-L/opt/local/include to no avail.  (It's 
unclear to me whether or not this is what the instructions meant since they 
were not explicit.)
