I had no problems here, but you should use the package ps4pdf,
it makes life easier. With the script and the config file from
http://perce.de/LaTeX/ps4pdf
you can insert \savePics at the end of the doc to get _all_
PSforPDF environments as pictureXX.eps. At least you get
a file <filename>-pics.pdf
I'll send you both as private mail.

I played a bit with your code. multido is a nice tool.
