Hello. 
In the following code, the circle (of center A) is drawn but with the 
\pstInterLC, I get an error. 
Compiling with ps2pdf gives the message "ps2pdf error" and no output; 
with XeTeX, I get a notification about a Ghostscript error and an output 
without the intersection points. 


\psset{unit=1cm} 
\pspicture(-3,-2)(9,3) 
\psplot{-3}{9}{x 3 div}\psplot{0}{9}{x 3 div 2 sub} 
\rput(7,2.5){$\mathscr{D}$}\rput(8,0.5){$\mathscr{D}'$} 
\pstGeonode[PosAngle=135](2,-1){A} 
\pstGeonode[PosAngle=100](0,0){B}(6,2){B'} 
\pstGeonode[PosAngle=300](6,0){C'}\pstGeonode[PosAngle=300,PointName=none,PointSymbol=none](0,-2){C1}
 
\pstProjection[CodeFig=true,PosAngle=300]{C'}{C1}{B}[C] 
\pstMiddleAB[CodeFig=true,PointName=none]{B}{C}{O1}\pstMiddleAB[CodeFig=true,PointName=none]{B'}{C'}{O2}
 
\pstLineAB[nodesep=-1]{O1}{O2} 
\pstCircleOA[Radius=\pstDistAB{B}{C} 2 div]{A}{} 
\pstInterLC[Radius=\pstDistAB{B}{C} 2 div]{O1}{O2}{A}{}{O}{O'} 
%\pstCircleOA{O}{A} 
\endpspicture 

Any idea ? 
Thanks 

Philippe
