W more-than-one-patch-system

Either the build-dependencies list more than one patch system or the package uses the 3.0 (quilt) source format but also has a dependency on dpatch. It's unlikely that you need both patch systems at the same time, and having multiple patch systems in play simultaneously can make understanding and modifying the source package unnecessarily complex.
