[OS X TeX] Why this .ps file can not be viewed?

[Leo]

Hello all,

A .ps file exported from Emacs somehow can not be viewed in Preview.app.
If I run pstopdf in Terminal.app to convert it into .pdf file, it can
not be viewed either.

Any .ps expert can shed some light on this? I have attached a sample .ps
file.
