See bug 225010. A port I am submitting crashes with the version currently in the ports tree; this version works fine.
Could you use devel/arcanist, or at least generate a diff with full context like it does, with svn diff -x -U9999 or git diff -U9999.
Regenerate using git diff -U9999. Also remove superfluous USES python version.
Regenerate with devel/arcanist
Refresh based on current ports tree revision and use PY_FLAVOR for dependencies
