Yes, NFlick was compiled on scirocco and the application manager will
not allow it to be installed on mistral. The problem here comes from the
${shlibs:Depends} expansion in the package control file. 

Also, it's true that package doesn't "need" the new hildon-libs version.
There were not any API-breaking changes in hildon-libs happening. 

Speaking more globally, we don't yet have any policies here. According
to the SDK team, we're not supposed to maintain any API compatibility
between releases. This is, however, something that has been "silently
assumed" rather than "consciously decided". 

Hopefully the API rolling process will become more clear in future, but
for now please bear with us.
