I don't know what kind of constraints you're dealing with, but the correct
way to handle an eps file (i.e. make it display) would be to actually
embed it in what is essentially a dummy .ps file, e.g. take the eps data
and surround it with the minimal ps header and footer necessary and then
process that instead of the original. (The problem you're having is rooted
in the fact that you're trying to treat an eps file like a ps file, so the
solution is to use the eps to make a real ps file).
