Bug#728588: FTBFS: test requires internet connectivity

[Felix Geyer]

Package: libnet-https-nb-perl
Version: 0.20-1
Severity: serious
Justification: fails to build from source

This package requires internet connectivity for its test suite
to pass. Package builds must not not rely on external network
connectivity, but should be self-contained.
