Description of problem:
Cannot install a customized rgb.txt file because the /usr/share/X11/rgb.txt 
file is ignored by the X server.

Version-Release number of selected component (if applicable):
Red Hat Enterprise Linux 5 Server running Xorg 7.1.1

How reproducible:


Steps to Reproduce:
1.  Edit the rgb.txt file, changing the 'Blue' and 'blue' entries to '255 0 0'.
2.  Start the X server.
3.  Create an xterm with the following command: 'xterm -fg blue'.
  
Actual results:
The xterm window appears with blue foreground text.

Expected results:
The xterm window should appear with red foreground text, since the rgb.txt was 
edited to associate the name 'blue' with a red color '255 0 0'.

Additional info:
No other copies of rgb.txt reside in the system.  Also, there were no errors in 
the /var/log/Xorg.0.log file.  RgbPath is set to '/usr/share/X11/rgb' in the 
xorg.conf file.
