I'm trying to use the sagetex style file in LaTeX. After trying to process the example.tex file provided with sagetex, I get error messages in the log that say to "Run Sage on example.sagetex.sage".

On my OS X system, Sage is installed as a clickable .app. After I start the app, I know how to start a Terminal command session of Sage by using the right-click menu from the Sage icon in the dock.

But how do I process such a .sage file in there?

If your Sage app is /Applications/Sage.app, for example, then from a Terminal window, run

$ /Applications/Sage.app/Contents/Resources/sage/sage example.sagetex.sage

You can instead add the directory /Applications/Sage.app/Contents/Resources/sage to your $PATH, and then you'll be able to do

$ sage example.sagetex.sage

Actually, once you add the sage directory to your $PATH, if you have latexmk, you can just do

$ latexmk example.tex

and it will run LaTeX and sage as many times as needed for the document (and also bibtex and any other needed TeX components).

I didn't know latexmk will run sage for you. Does it need special configuration, because the one I have installed (from MacTeX) doesn't seem to do it automatically?

Hmm. I seem to have some customizations in my .latexmkrc file, apparently downloaded from https://bitbucket.org/ddrake/sagetex/wiki/UsingSageTeX.

I should have thought to look there. Thanks.

On my machine, this setting (with others) was also available in `[TexLive2011Path]/texmf-dist/doc/support/latexmk/example_rcfiles `

I would also add `push @generated_exts, "sage";`to the .latexmkrc file, it should prevent latexmk from trying to run sage on the .sage file before the first latex run (useful in case there was a syntax error in your sage code for example).

If you just double-click the sage file that will run it with Sage.app.

If you use Emacs and AUCTeX, then I'm working on support for automatically detecting and running Sage as necessary, together with support for automatically finding the sage executable in Sage.app.
