pst-fractal defines also the optional argument Radius. This is the reason,
why you have to use

\psset[pst-eucl]{Radius=\pstDistVal{3}}



\documentclass{article}
\usepackage{pst-eucl}
\usepackage{pst-fractal}
\usepackage{auto-pst-pdf}
\begin{document}
\begin{pspicture}[showgrid=false](-4,-4)(4,4)
\pstGeonode(0,0){O}
\psset[pst-eucl]{Radius=\pstDistVal{3}}
\pstCircleOA{O}{}
\end{pspicture}
\end{document}
