Thanks, Herbert, for making effort on a solution. The new prologue file
seems to allow for using \pssin just once. If it appears a second time
it bombs again:

\documentclass{article}
\usepackage{pstricks}
\usepackage{pst-coil}
\begin{document}
\begin{pspicture}[showgrid=true](0,0)(9,7)
\pscustom{%
\psline(0,4)(2,6)%
\pssin(2,6)(6,6)%
\psline(6,6)(8,4)%
\pssin(8,4)(8,0)%
\psline(8,0)(0,0)%
}
\end{pspicture}
\end{document}
