All reports of source-contains-prebuilt-yapp-parser for the archive. The extended description of this tag is:
The source tarball contains a prebuilt Parse::Yapp parser. This is usually left by mistake when generating the tarball without first cleaning the source directory. You may want to report this as an upstream bug if there is no sign that this was intended.
Please build the parser from source.
Refer to https://bugs.debian.org/921080 for details.
