Error running app-text/ding: Unknown color name "white"

[jgreen]

I've been a happy user of the app-text/ding German/English dictionary for some time. Somewhat recently I updated some packages though and now ding no longer runs, with the error:

Error in startup script: unknown color name "white"
(processing "-background" option)
invoked from within
"frame .search -background white"
(file "/usr/bin/ding" line 1692)

I tried modifying the offending line in /usr/bin/ding, but then it goes on to complain about additional colors. Doing a search I came across other posts related to color issues, where /usr/share/X11/rgb.txt needed to be symlinked to other paths.
ln -s /usr/share/X11/rgb.txt /usr/lib/X11/
ln -s /usr/share/X11/rgb.txt /usr/X11R6/lib
ln -s /usr/share/X11/rgb.txt /etc/X11/
ln -s /usr/share/X11/rgb.txt /usr/lib/

Also found a mention of deleting the ~/.dingrc which I did. The problem persists though. I imagine its some sort of tk issue, but I'm at a loss of how to fix it, and I really want ding back Any ideas?

maybe you could look in your xorg.conf if this is present:

Section "Files"
RgbPath "/etc/X11/rgb"

Thanks for the reply! I was just about to write that I had that line in my xorg.conf and it still didn't work, but then realized that by adding the correct symlinks it may now work (since I hadn't logged out of X before when I was testing it). Sure enough, it worked! Thanks for the input, it did turn out to be related to that, and now I know there should be such a line in the xorg.conf. Although I've been working with Linux for over 10 years, I still doubt I would miss the X windows config file if it died, or at least had front ends that worked and were dynamic without having to restart things. Fortunately more things are going that direction.
