However, be aware that this is NOT standard GNU make 3.81 as provided by GNU. This instance of GNU make has some kind of changes added by Apple. I don't know the details but in the past I've had problems reported with this version of GNU make which we could not reproduce using standard GNU make 3.81. Apple will never ship a newer version than this, because starting with GNU make 3.82 we switched to using GPLv3. So if you want a newer version of GNU make, ever, you'll have to get it elsewhere. > maybe the users have to consider to use homebrew or something like > that, although I don't know manual installation of newer GNU make to > /usr/bin has a harmful impact... I'm no expert but I'm confident that neither MacPorts nor Homebrew overwrite utilities in /usr/bin. Instead, you need to set your PATH properly to choose the one you want.
