I had this same question about RH 7.2 around a couple of months ago. *Here's a response from Psycho that helped a lot.
"I just redid this because I reinstalled and clobbered my ttf's...
I had installed ttf's with Linux, so there *was very little to actually do.
copy ttf's from WinDoze/fonts to /usr/share/fonts/default/TrueType
cp fonts.scale to fonts.sc_save
cp fonts.dir to fonts.dr_save
I'm not paraniod, I just cover my a$$
in /usr/share/fonts/default/TrueType do the ttmkfdir > fonts.scale and mkfontdir as su
verify the line [ FontPath *"unix/:7100" ] in /etc/X11/XF86Config-4
also verify /usr/share/fonts/default/TrueType is in the catalog
section of /etc/X11/fs/config (entries are seperated *with comas).
(re)startX and enjoy
I had my fonts installed and working perfectly in under 10 minutes.
