This is a similar extended documentation/tutorial material like app-doc/gimp help. (kicad has a doc flag to build internal documentation). Should be only installed when the user specifically requests it. This is currently blocked on missing dblatex package #129368. Reproducible: Always
Missing perl dependency Unicode::GCString is blocking the build of this package.
As it turns out Unicode::GCString is part of dev-perl/Unicode-LineBreak, so build is unblocked, no need for new perl module ebuild.
