The post-build tests were failing on tens of errors like:
t/07_bugreport.t ..................... Can't locate Mail/Message/Field.pm in @INC (you may need to install the Mail::Message::Field module) (@INC entries checked: lib /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.38.2 /usr/local/share/perl/5.38.2 /usr/lib/x86_64-linux-gnu/perl5/5.38 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl-base /usr/lib/x86_64-linux-gnu/perl/5.38 /usr/share/perl/5.38 /usr/local/lib/site_perl .) at lib/Debbugs/MIME.pm line 57.

BEGIN failed--compilation aborted at t/07_bugreport.t line 19.
Add the missing dependency to overcome this and get the tests passing.
Note that the tests still emit multiple times this warning which
warrants additional follow-up later:
