Comment (by ryandesign):

 The issue is not OS-specific. The problem is caused by scons 3.0.0. I see
 the issue on macoS 10.12 when building from source. You won't see it on
 10.12 or below if you have a MacPorts configuration that receives our pre-
 built binaries, which were built before scons 3.0.0 existed.

 The [http://scons.org/doc/3.0.0/HTML/scons-user/ch08s02.html documentation
 for scons 3.0.0 shows] `print` being used as a function—and shows
 "SyntaxError: invalid syntax" occurring as a result! It's as if the
 documentation is generated by actually running scons and showing its real
 output, and nobody noticed that `print` doesn't work anymore.
