python25 is not supported on Yosemite or later

Hello --

This Python 2.5 error has been pervasive in my trying to install ports, & this gcc5-related error is the most recent instance. Will you please help?

You are on macOS 10.12 Sierra. As the error message says, python25 is not supported on OS X 10.10 Yosemite or later, so uninstall it:

sudo port uninstall python25

If you want to use python 2.x, use python27 instead (or python26, if you really want).
