Copying the exported file to flash, opening on Linux, and copying the Masters folder out got me all my JPEGs. Copying the photo folders back to the flash drive allowed me to bring them back to my Mac in a usable form.
Played around a little and found this other solution:
After exporting your library, rename it to have the ".zip" extension. Double click it to get a new file with the extension ".zip.cpgz". Double click that and you'll get the top level folder out. (Mine had the file extension ".zip" on it, but it was just a folder. Open that folder and you'll find the Masters folder. There your JPEGs are!
