@mojavelinux this may be happening somewhere above prawn-svg. When I do

ruby -r prawn-svg <<EOF
Prawn::Document.generate("test.pdf") do
  svg IO.read("pipelinemesh.svg"), position: :center
end
EOF

(where that's one of the files asciidoctor reports this error on), there's no complaint generated and the resulting PDF looks OK. When I try to run asciidoctor-pdf on the actual document, though, these complaints pop up. So maybe asciidoctor-pdf is the right place to file an issue?
