The application raised an exception with the message:

pdflatex: rendering error

Can you post the output that pdflatex gave as well?

3

Where would I find that? Would it be in the Terminal window?

4

Yes, it should show up there.

Found it, seems like it can’t find pdflatex. I downloaded and installed MacTex.
But

% which pdflatex
pdflatex not found

And

pollen: rendering /Tutorial/cv.poly.pm as pdf
/bin/sh: pdflatex: command not found
Servlet (@ /Tutorial/cv.pdf) exception:
pdflatex: rendering error
