More info:
N: 
N:    The referenced file has a time stamp older than June of 2006 and the
N:    package does not build-depend on autotools-dev or automake and therefore
N:    apparently does not update it. This usually means that the source
N:    package will not build correctly on AVR32, for which a Debian port is
N:    currently in progress, and may not support other newer architectures.
N:    
N:    Read /usr/share/doc/autotools-dev/README.Debian.gz (from the
N:    autotools-dev package) for information on how to fix this problem. cdbs
N:    will automatically update these files if autotools-dev is installed
N:    during build, but the build dependency on autotools-dev is still
N:    necessary.

N:    Severity: normal, Certainty: possible
