Of course, the binary would be released versions (eg. 2.15.2) rather than R patched.

Okay, thanks.  I shall transfer this discussion over to r-sig-fedora.

For the record I did indeed have xorg-x11-font-utils already installed.  
I got the
xorg-x11-fonts-75dpi and  xorg-x11-fonts-100dpi packages via

     sudo yum install xorg-x11-fonts-75dpi.noarch

and

     sudo yum install xorg-x11-fonts-100dpi.noarch

However when I tried my toy example I got the warning message:

> In text.default(2, 6, "Oh, hell!", cex = 2) :
>   X11 used font size 25 when 28 was requested

and no actual characters appeared in the plot but rather 4 (???)
little rectangles outlined in dotted line type.

So some progress, but not there yet.

     cheers,

         Rolf
