mpage vs. gs vs. gv [ & ggv & kghostview ]

[Jonathan Ryshpan <jonrysh@xxxxxxxxxxx>]

mpage generates files that gv won't display, but gs will.  For the
simplest example 
        $ cat /dev/null | mpage > foo.ps
        $ gs -sDEVICE=x11 foo.ps    # works fine -- emits messages about substituting fonts
        $ gv foo.ps                 # produces error messages and fails
        
Here are the error messages:
        > ERROR: /undefinedresource in --findresource--
        > Operand stack:
        >    uniks   Baekmuk-Batang-UniKS-UTF8-H   Font   Baekmuk-Batang-UniKS-UTF8-H   (Baekmuk-Batang-UniKS-UTF8-H)   14   Baekmuk-Batang   UniKS-UTF8-H   UniKS-UTF8-H   Baekmuk-Batang   Baekmuk-Batang   Baekmuk-Batang   --nostringval--   (r)   --nostringval--   CMap   (r)   CMap   (r)

You can see the same problem with an actual file with data in it:
        $ date /dev/null | mpage > foo.ps
        ...
        
ggv and kghostview also fail, but don't show errors.

Any ideas?
