Macports fails to build in macOS 10.12 Sierra

[Artemio González López]

I’ve installed the Developer preview of macOS 10.12 Sierra, and I have been trying to rebuild my MacPorts installation following the Migration instructions at MacPorts. The problem is that ./configure —enable-readline fails with the error message found at the end of the complete output of this command below). I of course know that I am using a beta system, so that I’m not entitled to any support from the MacPorts team. However, I would really appreciate any pointers as to how to fix this (if  possible).

Thanks a lot,

Artemio
