[Debian-med-packaging] Bug#860704: python-pysam: FTBFS on i386: build-dependency not installable: bcftools (>= 1.3.1)

[Lucas Nussbaum]

Source: python-pysam
Version: 0.10.0+ds-1
Severity: serious
Tags: stretch sid
User: debian-qa at lists.debian.org
Usertags: qa-ftbfs-20170418-i386 qa-ftbfs
Justification: FTBFS in stretch on i386

Hi,

During a rebuild of all packages in stretch (in a stretch chroot, not a
sid chroot), your package failed to build on i386.

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.
