Make: use npm update for devel target package.json says we want coffee-script >= 1.6.1, so that's what `make devel` should install (the newest version): since .js source is tracked, there's no risk of running into breaking changes in coffee-script outside of test environment. But running into such changes during tests is OK and even potentially desirable.
