Since the compilation fails because pdflatex can't find the tools it
needs in order to convert between the different formats, I would say
it is going to happen in all cases. Oh, and by the way, the example
file in /u/s/d/texlive-pstricks-doc/latex/pdftricks/test.tex.gz can't
compile (I can't find, nor 'apt-file search' can, the pst2pdf script).

Actually, I ran into this while trying to draw Markov chain. Here is
a simple example :

------------8<--------------

\documentclass{article}
\usepackage{pdftricks}
\begin{psinputs}
  \usepackage{pst-all}
\end{psinputs}

\begin{document}
Une chaine de Markov toute simple :

\begin{pdfdisplay}
  \psmatrix[mnode=circle]
    1
  \endpsmatrix
  \psset{arrows=->}
  \nccircle{1,1}{0.4cm}\taput{1}
\end{pdfdisplay}

\end{document}

---------------8<------------

When trying to compile it with neither ps2eps nor
texlive-extra-utils, compilation fails with :

sh: ps2eps: command not found
rm: ne peut enlever `a-fig1.eps': Aucun fichier ou répertoire de ce
type

(rm : cannot remove `a-fig1.eps': no such file or directory).

The same error happens with the test.tex.gz included as an example by
the package.

I can provide the full logs, if you need them.

Note that the Markov chain is correctly built (and is staying in
a-fig1.ps), but hasn't been converted to a suitable format and
hasn't been included in the final PDF document.

After installing ps2eps (and, just in case, moving a.tex to another,
clean directory), compilation fails with :

Creating output file a-fig1.eps...ready.
sh: epstopdf: command not found

After installing texlive-extra-utils, the document is built as
expected.

OK. I actually thought of a Recommends, but Suggests is fine. Maybe
also a comment in the description ?
