font corruption in X11

[Giorgos Keramidas]

I've tried rebuilding all my ports today, and noticed that fonts are
missing glyphs now :-/

The following seems to be a snippet that seems relevant, but before I
try to rebuild it all (it takes a few hours here), has anyone seen this
already and managed to find a fix/workaround?

: perl  /usr/X11R6/bin/ucs2any 6x10.bdf /usr/X11R6/lib/X11/fonts/util/map-ISO8859-4 ISO8859-4

The fonts lack certain characters after this.  A screenshot of XTerm
started with 'xterm -fn fixed' that shows this can be found at:

Any ideas what causes this?
