Thanks.

Yes the script gets to the print "Error b: $err\n"; line, which shows the output:

Error b: Exception 435: unable to open file `Image::Magick::Q16' @ error/Q16.xs/XS_Image__Magick__Q16_Read/13529

That's even after adding the CARP lines to the beginning of the script as you've recommended. So adding CARP provides no additional output.

On the one system,

$ apt-cache policy libimage-magick-perl | head -n 3
