[pstricks] pstricks-add makes latex to complain

[Marcelo Matus]

When using the last pstricks distribution
and the last xkeyval distribution, pstricks-add
makes latex to complain.

For example, when compiling the pstricks-add example

 latex doppellog.tex

This is TeX, Version 3.14159 (Web2C 7.4.5)
