Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

Relevant part (hopefully):

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures. The build
was done with DEB_BUILD_OPTIONS="parallel=4", so if your packaging tries
to support this, it might be a good idea to explore whether this might
be the cause of the failure.
