[pstricks] pstricks pst-func \rput conflict

[berginj at econ.queensu.ca]

In the small latex file below, I have both packages pst-func and pst-all.
When run with ``pst-func'' all labels p_1, p_2, x_1, x_2 are placed at
(0,0), whereas ``pst-all'' places them properly. When both pst-all and
pst-func are present, the labels are also misplaced.  In need to use both
packages in my file.  Is there a simple explanation and solution?
