FuzzyOcr: Cannot exec jpegtopnm, skipping image

Hi, I am trying to set up FuzzyOcr, which is a SpamAssassin plugin. It is supposed to add image recognition ability to SpamAssassin. Unfortunately, it seems to have a lot of dependencies, some of which, also have dependencies!

I believe I have installed all the dependencies and components, but in my maillog I'm seeing this,
