I get this too, but it is preceded by another glitch.

Ensuring that the TeXshop engine uses   -shell-escape
gets past this check smoothly.


Now I get messages:

But isn't the purpose of  auto-pst-pdf.sty   to cause
an auxiliary run of LaTeX, in .dvi mode, to convert the
contents of special environments to PDF via PostScript?

When you have no such environments, as in this overly-simple
test file, then using the package is not relevant at all.


Now auto-pst-pdf.sty  doesn't do the real work; that is done
by  pst-pdf.sty , so you can simplify the test a bit and still 
get the same messages.

Here's the output tracing:

which lets you see the 2 \special commands which are for 
establishing the page rotation angle.


So the question is why are these being placed in the PDF,
when they can only have relevance in the auxiliary .dvi ?

Or maybe they are to establish some parameters that the embedded
PDF images can reference, to adjust orientation to the page
that they are on. But if pdfTeX discards them, then this cannot
work. But maybe pdfTeX gets the angles right anyway, and they
are really designed for use with a different driver?

Just a bit of guessing here.
Someone else should be able to clarify this.
