Comment (by cjones051073):

 I suspect part of the problem here is the 10.12 buildit actually has Xcode
 9 installed, not 8. See for instance

 {{{
 DEBUG: Starting logging for py37-yt
 DEBUG: macOS 10.12 (darwin/16.7.0) arch i386
 DEBUG: MacPorts 2.5.3
 DEBUG: Xcode 9.2
 DEBUG: SDK 10.12
 }}}

 just taken from a recent build.

 I have seen evidence previously that this information somehow gets 'baked'
 into the gcc compilers, so when you install one from the binary tarball
 made from the builedbot, it expects to use the cctools from Xcode 9, which
 you don't have.

 Not sure the right approach here. Is Xcode 9 the 'recommended' one on
 10.12 ? If yes, upgrade yours. If not, I wonder why the buildbot has it.
