Patrice,

the xdvipdfmx program is not complete compatible to dvips.
This is the case for placing objects relativ to nodes.
\pcline defines its coordinates first as internal nodes
@@A and @@B. We can use this for a new macro. Maybe that I
will write a pstricks-xetex.tex which wioll collect all such
stuff.

\documentclass{minimal}
\usepackage{pst-node}
\makeatletter
\def\NCput{\pst at object{NCput}}
\def\NCput at i#1{%
   \begingroup
   \use at par
   \pst at getcoor{@@A}\pst at tempA
   \pst at getcoor{@@B}\pst at tempB
   \if at star\def\next{\rput*}\else\def\next{\rput}\fi
   \next(!
   	  \pst at tempA /yA ED /xA ED
   	  \pst at tempB /yB ED /xB ED
   	  xA xB add 2 div
   	  yA yB add 2 div \tx at UserCoor){#1}
   \endgroup
   \ignorespaces
}
\makeatother
\begin{document}

\begin{pspicture}[showgrid](10,5)
   \pcline{<->}(1,1)(7,1)\ncput{$\Delta y$}%
   \pnode(0,1){A}
   \rput(0,1){\pcline{<->}(1,1)(7,1)\NCput*{$\Delta y$}}
\end{pspicture}

\end{document}
