There is no iso8859-13.enc or iso8859-13.enc.gz in /usr/X11R6/lib/X11/fonts/encodings, from XFree86-4.0.1-1 rpm, although this file is included in XFree86 4.0.1 distribution.
There were no iso8859-13.enc in xc/fonts/encodings/Imakefile of XFree86 source. But it is now in XFree86 4.0.2, so I think you can close this bug.
Ok, thanks. Also, just for your info.. XFree86 4.0.3 is out now at: ftp://people.redhat.com/mharris If you check it out be sure to get Mesa as well. Enjoy! TTYL
