This can't work.  Try to RTFM, understand why and use:

%----------------------------------------------
\documentclass{article}
\usepackage{ps4pdf}
\PSforPDF{%
\usepackage{pst-plot}
\usepackage{pst-text}}
\begin{document}
\PSforPDF{%
\psset{unit=1cm}
\begin{pspicture}(-0.25,-2.25)(6.25,2.25)
\pstextpath[linestyle=none]%
{\psplot[linewidth=1pt,%
linestyle=dotted,%
plotpoints=300,%
xunit=0.015,%
yunit=2]{0}{400}{x sin}}
{\LARGE TUGboat, the journal
of the \TeX{} Users Group}
\end{pspicture}}%
\end{document}
%------------------------------------------------

instead.
