Hi,

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

Relevant part (hopefully):

A list of current common problems and possible solutions is available at

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.
