Bug#1023231: cimg: autopkgtest failure everywhere but on amd64: './libHalf.so': File exists

[Paul Gevers]

Source: cimg
Version: 3.1.6+dfsg-4
Severity: serious
User: debian-ci at lists.debian.org
Usertags: fails-always

Dear maintainer(s),

You recently added an autopkgtest to your package cimg, great. However, 
it fails everywhere but on amd64. Currently this failure is blocking the 
migration to testing [1]. Can you please investigate the situation and 
fix it?

I copied some of the output at the bottom of this report.
