[OE-core] image build with python fails due to missing berkeley db 5.3

Thanks Martin - is there also a version specific variant of RDEPENDS that can be added to python-bsddb to get this working without manual intervention?

I see that recipe-support/db/db_5.3.28.bb already has --enable-cxx so I am a bit confused why it failed

It seems unfortunate that python-bsddb needs libdb 5.3 when everything else in the master is using 6.0. What would need to change in the recipes-devtools/python/python/python-2.7.3-berkeley-db-5.3.patch to get it to work with libdb 6.0?
