Thanks, this certainly helps me on my way. I don't have a lot of choice in terms of using diagnostics in the app - it's a dependency somewhere deep in the dependency tree. What I can do is change diagnostics.pm or Config.pm to either not look for perldiag.pod or to include it in the par app (and update a local Config.pm accordingly). Neither is the ideal solution, but I can stop pulling my hair out now. Thanks!
