for a package I am working on, I am setting versioned Build-Depends, to avoid using newer libav versions which would break compilation, e.g.:libavcodec-dev (<< 6:9)Compilation under pbuilder for Sid goes fine, but the binary packages are still allowed to be installed with newer libav binary packages:libavcodec53 (>= 6:0.8.3-1~) | libavcodec-extra-53 (>= 6:0.8.5)
A well-behaved shared library package won't break binary compatibility without changing package name. In fact, the package name has changed to libavcodec54. So nothing wrong with the dependency as far as I can tell.
