So that would build/use the libmozjs from the sbbs repo. One thing to try would be to install/use the libmozjs package for your OS/platform (or similar), instead:

Those instructions previously included teh JSINCLUDE and JSLIB options to point to the installed/system libs and header files for libmozjs.
