@willtp87 I created a [new test repository](https://github.com/slangerx/islandora_solution_pack_large_image_unpatched), one that's an exact copy of Islandora/islandora_solution_pack_large_image. It does *not* include my pull request, yet it's [failing Travis CI in the exact same way](https://travis-ci.org/slangerx/islandora_solution_pack_large_image_unpatched). So the failure is not due to my latest commit but to something else in the codebase.

A pull request was merged with Islandora/islandora_solution_pack_large_image in the last seven days. Eight days ago, the build worked fine. Maybe a problem was introduced with this latest merge?
