The message stating that Python was compiled with gcc-4.2 is strange. That would not be the case on OS X 10.9.5. OS X 10.6.8 was the last OS X version to feature gcc-4.2. Are you sure you are running MacPorts python? What version of Xcode do you have installed?
Don't try to directly run files inside the MacPorts ports tree; they're not for you; they're for MacPorts to use when installing ports. Each Python module or project will typically include its own setup.py file tailored to that project's needs; that's the setup.py you'll be using to build that project.
Don't forget to use WikiFormatting when writing in Trac.
