I guess you're right. Linking in programs feels safer, but this is 
acceptable. I already have fondu in the standalone .dmg. Can you prepare 
a fondu patch?  (you need to make a copy of your source dir first, since 
CVS is down.)

At the moment, I have

  (define (handle-mac-font name file)
    (open-input-pipe
     (format "./showfond ~a | grep FontName=" file))
       .. todo..
    )


  ..

        ((and bare-file-name (string-match "\\.dfont" bare-file-name))
         (handle-mac-font name bare-file-name))

        ((and bare-file-name (= (stat:size (stat bare-file-name)) 0))
         (handle-mac-font name bare-file-name))
        

handle-mac-font should

 - make temp directory
 - run fondu to extract the files
 - determine which file should be loaded for the given font name
 - decide whether to do ttf->pfa or pfb->pfa
 - cleanup the temp dir
