** The GD library is required for rateup to compile.
   Get it from <a href="http://www.boutell.com" target="_blank">http://www.boutell.com</a>, compile it and
   use either --with-gd-lib=DIR and --with-gd-inc=DIR to specify
   its location. You might also have to use --with-z-inc, --with-z-lib
   and --with-png-inc, --with-png-lib for gd versions 1.6 and higher.
   Check config.log for more information on the problem. If your system
   has libgd installed, you probably mis the gd.h header file.
 
   Consider following the instructions in doc/unix-guide.txt
