I had the same problem. My solution was to patch the
procedure PRE_FONT_OPEN in font_open.c line 714 following.


/* Beginn von Elmar geaendert */
#define RUNDE(a)        ((int) ((a) + 0.5))
            Sprintf(mkpk, "%s %s %d %d %s", MAKEPKCMD, font, RUNDE(mag / 5.0),
                pixels_per_inch, magstring(RUNDE(mag / 5.0)));
/* Ende von Elmar geaendert */
