[racket] sandboxing issue while trying to print slideshow slides

Hello,
  I'm trying to make a PDF of a slideshow presentation that uses Jay McCarthy's slideshow-latex package from PLaneT.  I seem to be running up against slideshow's sandbox: the package needs to run LaTeX and generate some image files, and so slideshow is hitting a "slide program attempted to execute external code" error.
  Is there a way to disable sandboxing in the standalone slideshow program, print slides from within DrRacket, or otherwise get the PDF I want without having to make extensive changes to my source files?  Thanks in advance!
