Bug #121922 for Image-Sane: t/81_scanimage-perl.t may fail

t/81_scanimage-perl.t is successful on most of my Linux smoker systems (Debian jessie, Debian stretch, CentOS 7). It just fails on my Ubuntu 16.04 smoker (test log see below). It seems that on this smoker system scanimage is not installed. libsane-dev is installed, but the scanimage binary is located in the package sane-utils. Maybe the installation instructions should be updated, or t/81_scanimage-perl.t should skip tests if scanimage is not available. ... sh: 1: scanimage: not found identify: improper image header `out.pnm' @ error/pnm.c/ReadPNMImage/282. # Failed test '--device=test > out.pnm; identify -format '%m %G %g %z-bit %r' out*.pnm; rm out*.pnm' # at t/81_scanimage-perl.t line 32. # got: 'PGM 157x196 157x196+0+0 8-bit DirectClass Gray ' # expected: '' # Failed test '--device=test --test 2>&1' # at t/81_scanimage-perl.t line 32. # got: 'scanimage: scanning image of size 157x196 pixels at 8 bits/pixel # scanimage: acquiring gray frame, 8 bits/sample # scanimage: reading one scanline, 157 bytes...
