this is due to xmkmf is broken for MacOSX 10.3.9
% tcsh
% xmkmf
tcsh: usage=usage:  /usr/X11R6/bin/xmkmf [-a] [top_of_sources_pathname [current_directory]]:

but with bash:
% bash
takuboku:/Volumes/OpenOffice.org/Panther/2.0/work/OOo_2.0.0rc3_src/nas maho$ xmkmf
imake -DUseInstalled -I/usr/X11R6/lib/X11/config
imake: No such file or directory
imake: No description file.
  Stop.                   

apparently xmkmf (of MacOSX 10.3.9) is broken :(

% head -n 2 /usr/X11R6/bin/xmkmf
#pragma GCC set_debug_pwd "/private/var/tmp/X11/X11-0.30.obj~2/xc/config/util"
#!/bin/sh      

following patch solves this problem.
