Note that SlicerPathology has not been functional for quite some time. The underlying issue has been discussed on this forum: Pathology module install fail due to sliceWidget attribute error, and documented in this GitHub issue: Module won't start - testing code committed by accident? · Issue #100 · SBU-BMI/SlicerPathology · GitHub.
More recently, build errors cropped in, most likely due to the recent upgrade of the Slicer dependency libraries - see dashboard here.
