[oe] Python exception running step do_package_update_index_ipk in OE classic

[Craig McQueen]

I'm trying to build OE classic for i.MX28, following instructions at:
http://www.imxdev.org/wiki/index.php?title=All_Boards_OpenEmbedded

I'm trying to run:
  bitbake bootstrap-image

It is failing on a step do_package_update_index_ipk when calling Python program opkg-make-index. See error below.

The problem is when it calls subprocess.check_output(), but check_output() is only in Python 2.7, but not Python 2.6.

On my machine, Python 2.7 is installed, however it seems that OE must be running Python 2.6. I see that OE builds Python 2.6 in tmp/work/i686-linux/python-native-2.6.6-ml12.0.

What would be a good way to fix this?

Regards,
Craig McQueen
