version 2.19 broke compatibility with python 2.6

[david-richer-adsk]

Hi guys,

We now get the following error when installing package that pull the latest (2.19) version of pycparser on python 2.6.

File "/usr/lib/python2.6/site-packages/pycparser/__init__.py", line 14, in <module>
        from subprocess import check_output
    ImportError: cannot import name check_output

We know that python 2.6 is super old but it's still the version ship with CentOS 6. Feel free to drop support, a note about this in the change log would be appreciated.

Thanks for your time,
David

Sorry for the breakage. I haven't been testing pycparser with Python 2.6 for years, and minimal 2.7 is noted in the README. I will put a note in CHANGES, in any case
