Thank you for your detailed reply. Good to know about Rasterize, however, 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:

plot = Plot[x, {x, -0.1, 0.1}, AxesLabel -> {eps, SUM},
BaseStyle -> {FontSize -> 10}]
Export["plot.eps", plot]

\psfrag{eps}{$\epsilon$}
\psfrag{SUM}{$\Sigma$}
\includegraphics{plot.eps}
