If you remove the following lines from the resulting ps file, you probably have
much better luck.

    /kanj /Ryumin-Light-H findfont 11 scalefont def
    /han /Ryumin-Light.Hankaku findfont 11 scalefont def
    /unijis /Ryumin-Light-UniJIS-UTF8-H findfont 11 scalefont def
    /uniks /Baekmuk-Batang-UniKS-UTF8-H findfont 11 scalefont def
    /unigb /BousungEG-Light-GB-UniGB-UTF8-H findfont 11 scalefont def
    /unicns /ShanHeiSun-Light-UniCNS-UTF8-H findfont 11 scalefont def

I beleive these fonts are needed for kanji support.
These fonts apperantly are not on your system, or al least not configured for
for gv.

I found myself deleting these line over and over again...
