[OS X TeX] sagetex and TeXShop

[Sette Diop]

Hello there!
There seems to be something broken in the automation of sagetex in TeXShop in recent updates.
Can someone out there help with this?
Thanks so much!

I just installed Sage (sage-5.9) in my MacBook Pro (Mac OS 10.8.3). I am using TeXShop 3.18.

- The source file is appended to this message
- The Engine drop-down menu is set to 'sage'.

The console says (among other things):

How do I run Sage on sage_example.sage? Isn't TeXShop supposed to send
this to Sage and get output from Sage without my intervention?

The whole source file is as below:

% !TEX TS-program = sage 
\documentclass{article}
\usepackage{sagetex}
\begin{document}
Using Sage\TeX, one can use Sage to compute things and put them into your \LaTeX{} document.
For example, there are $\sage{number_of_partitions(1269)}$ integer partitions of $1269$.
You don't need to compute the number yourself, or even cut and paste it from somewhere.
Here's some Sage code:

\begin{sageblock}
    f(x) = exp(x)*sin(2*x)
\end{sageblock}

The second derivative of $f$ is
\[
  \frac{\mathrm{d}^{2}}{\mathrm{d}x^{2}} \sage{f(x)} = \sage{diff(f, x, 2)(x)}.
\]
Here's a plot of $f$ from $-1$ to $1$:

 \sageplot{plot(f, -1, 1)}
\end{document}

When I run TeXShop here is the whole .sagetex.sage file:
