All reports of ancient-autotools-helper-file for the archive. The extended description of this tag is:

The referenced file has a time stamp older than year 2004 and the package does not build-depend on autotools-dev or automake and therefore apparently does not update it. This usually means that the source package will not build correctly on all currently released architectures.

For packages using debhelper, the tools from the dh-autoreconf package should handle this issue. cdbs will automatically update these files if autotools-dev is installed during build, but the build dependency on autotools-dev is still necessary.

Otherwise, read /usr/share/doc/autotools-dev/README.Debian.gz (from the autotools-dev package) for information on how to fix this problem.

Severity: important, Certainty: possible

Check: cruft, Type: source
