did you netpkg xorg-font* ? Some font packages aren't on the default install.
I had problems with emacs before installing some of them, now i've :
xorg-fonts-100dpi-7.1.1-noarch-1z40
xorg-fonts-misc-7.1.1-noarch-1z40
xorg-fonts-75dpi-7.1.1-noarch-1z40
xorg-fonts-scalable-7.1.1-noarch-1z40
xorg-fonts-cyrillic-7.1.1-noarch-1z40
some of them might not be usfull, but as i didn't have disk space problems for now, i don't really care
