 Replying to [comment:2 barracuda156]:
 >  I just don’t see the logic behind asking for an exotic compiler when
 gcc7 does the job and is required for numerous ports anyway.

 That was going to be precisely the reasoning I would cite for why apple-
 gcc42 should be used. It is the default MacPorts compiler on Tiger and
 Leopard and Snow Leopard. It comes with Xcode on Leopard and Snow Leopard.
 Why require the user to install another compiler port when apple-gcc42
 will do?

 > Perhaps it should at least check if macports-gcc-7 is already installed?

 You propose that `port` should behave differently depending on what you
 already have installed? No. See ReproducibleBuilds.
