Yup, GS 8.51 is installed and runs smoothly from a shell.
You might try the following. Open a shell and navigate to a PDF graphic
file of your choice. Then run
convert -verbose whatever.pdf whatever.ppm
and see what transpires. (I'm assuming that ImageMagick is on whatever
OS X uses for a command path.) If the conversion works, odds are the
problem is with the LyX setup. If it fails, odds are the problem is
with either the ImageMagick setup or whether it can find the GS library.
