gtk and fonts on OS X

[Allin Cottrell <cottrell wfu edu>]

I'm able to build and run my gtk app just fine on OS X 10.2.4 plus 
fink.  But I'd like to make the app available to people running 
OS X 10.3 Panther, with Apple's X11 but without fink.

I've made what is intent a stand-alone disk image (my app plus all 
the required gtk libraries).  But I'm hearing that the app won't run 
on account of a problem with fonts

  Cannot open fallback font, nothing to do

That is, gtk/pango can't find anything to map to Monospace or Sans.

Does anyone with OS X experience have any idea what might be 
wrong/missing here?  (The systems in question do have X11 
installed.)
