The attached patch to libXt 1.0.7 will list all fonts not found.

On my test system I get the following output:

Note that the whole GNU gv sources do not contain e. g. the string "KOI" 
(case independent) and therefore not "KOI8-R", so it's clearly the case 
that libXt+libX11 require that fontset - like I cited from the web site 
above.


It may help (but I do _not_ think it's a good idea, as it will 
completely break international mode) to remove

    XtSetLanguageProc(NULL, NULL, NULL);

from main.c.
