You are right, and actually crda (from meta-arago) already depends on 
python-m2crypto-native.
Anyway, it doesn't seem to be enough as my build failed, and I had to 
install my distro version of python-m2crypto to fix this (unless it got 
fixed as a side effect of re-running bitbake).

I might clean and rebuild everything, I thought I could update the 
layers without rebuilding everything from scratch, in theory it should 
work, but in practice I'm not sure it does, as I had a couple of issues 
(after my last update) that doesn't make sense to others (BlueZ version 
issue, Qt  and now crda).

Thanks,
Chris
