I checked with the internet. On year 2007 there is a similar question asked and it seemed that no further comments were given then. My guessing is that it involves input/output procedures and thus much complex to solve. http://www.latex-community.org/viewtopic.php?f=4&t=677 Now I understand why your problem arises. Well, latex-dvi2ps-ps2pdf is an old route, more favored routine is to use pdflatex and xelatex. I seldom use the old route now, only if I have eps to deal with. But that dilemma is solved too. The eps can be converted to pdf via eps2pdf package. Hope this info helps.
