radical solution

 Download and unpack the PSTRicks-TDS.tar to a directory
 cp ./PSTricks-TDS/tex/generic/*/*.tex .
 perl -pi.back -e 's/\ifx!#1/\ifx !#1/g;' *.tex
 rm -rf *.back
 cp /usr/local/texlive/2013/texmf-dist/tex/context/base/colo-rgb.mkii
./colo-rgb.tex
 run context

 change in m-pstric.* files ps2pdf to pstopdf

tanks a lot
