Build failure with python < 2.7: ImportError: No module named argparse

Hello, I'm the maintainer of youtube-dl in the MacPorts package management system. Building youtube-dl 2014.12.15 fails on Mac OS X v10.6 Snow Leopard as follows:

DEBUG: Executing command line:  cd "/Volumes/Data/macports/snowleopard/var/macports/build/_Volumes_Data_macports_dports_net_youtube-dl/youtube-dl/work/youtube-dl" && /usr/bin/make -w all PYTHON=/Volumes/Data/macports/snowleopard/bin/python2.7

ImportError: No module named argparse

I believe the problem is that make_contributing.py uses argparse, which is not included in Python until version 2.7; python on Mac OS X v10.6 is version 2.6.1. As you can see I have requested to use a MacPorts-installed copy of Python 2.7, but the youtube-dl build system is not making use of it. My first guess is that you could use $(PYTHON) instead of python in the Makefile to fix this.

Thank you for the report. I believe this to be fixed in youtube-dl 2014.12.16.
