I don't think that is the problem here. Are you using mathematica version
8? My suspicion is that there is some difference in how mathematica 8 creates eps files compared to earlier versions. Even simplest examples fail for me after upgrading to 8, say:

Hi,
I think my original post to mathgroup got lost, so please excuse possible double postings.
I can confirm this problem under Linux and Mathematica 8. The ps export apparently changed in this version. Strings are now exported as single characters rather than as the whole string (sorry for the handwavingexplanation, I know nothing about the innards of postscript), therefore replacement of multi-character strings breaks. I would guess that replacing single characters still works. My pragmatic solution was to go back to v.7 to export my graphics. However a fix or at least a workaround would be desirable, as I don't want to keep v.7 around forever.
Best regards,
Sebastian
