Xorg freezes on start

[=?ISO-8859-15?Q?Rapha=EBl=20Marmier=20]

Well, me again ;)

the dfports/x11-server/xorg-server built successfully. but when I try to 
run xorg -configure, the whole machine freezes. The last message is 
Couln'd open RGB_DB '/usr/X11R6/lib/X11/rgb'

Actually, there is no such file.

I might add that this is a SMP kernel.
