1. This package has a perl and a C version of the program, and you install the C one. Have you considered installing both and using the alternatives system to permit the user to choose?
Both implementation have identical functionality AFAICS, so I don't see the point of installing them both. How would the user decide which one they want?
2. Your autopkgtest test suite appears to test the perl version?
Hopefully not, because it's supposed to test the install packaged, and as you noticed, there's no Perl version there...
