I uploaded pstricks-add.tgz to the uk mirror.

this new version 2.72

• fixes a bug in psgraph
• has a new macro for drawing a step function for the lower and upper sums of mathematical functions

i have installed the new version and pushed it to the other ctan nodes; i've also updated the catalogue.
