Help with TCL/TK on centos 5.2 unknown color black - solved
check your /etc/X11/xorg.conf on the differents machines.
-> RgbPath "/usr/share/X11/rgb"
It was different between the two machines...
On the machine that worked the RgbPath was not specified.
It was specified on the machine that did not work...
I commented it out and rebooted and it started working.
