The *Messages* buffer did indeed show something:
"Failed to create dvi file from
/var/folders/zf/bgjm4tvs3wv_6q7_6z3b2nx00000gn/T/orgtex64181Q3t.tex"
Checking the log file in that directory, I saw squawking about missing "$"
signs around the mathematical expression. Adding these, so the block now
reads
#+begin_src latex :file test.png :results raw
$\frac{1}{2}$
#+end_src
it now compiles and displays perfectly.
Thanks!
