Thanks, I imported 'distutils' and that helped, but I still have problems with it.  Looking
at log.do_configure:
   checking for python... /local/rpi_2014-04-10/tmp/sysroots/x86_64-linux/usr/bin/python-native/python
   checking for python-config... /local/rpi_2014-04-10/tmp/sysroots/x86_64-linux/usr/bin/python-native/python-config
   Traceback (most recent call last):
     File "/local/rpi_2014-04-10/tmp/sysroots/x86_64-linux/usr/bin/python-native/python-config", line 6, in <module>
       from distutils import sysconfig
     File "/local/rpi_2014-04-10/tmp/sysroots/x86_64-linux/usr/lib/python2.7/distutils/sysconfig.py", line 22, in <module>
       PREFIX = os.path.normpath(sys.prefix).replace( os.getenv("BUILD_SYS"), os.getenv("HOST_SYS") )
   TypeError: expected a character buffer object

When I ran python-config before (original email), the results
were from outside the build environment, i.e. the command line
where I run 'bitbake'.  When do_configure() runs in my recipe,
the environment seems to be quite different.  If I try to run
python-config from devshell (for my recipe), it fails as above.

I'm sure I'm just missing something...

Thanks for the help
