lpvs is resporting wrong installed packages version in Ubuntu Utopic Unicorn

[alinefr]

As I though it was perl version related I installed perl 5.10.1 with perlbrew but still same effect:

Below it reports as if libgnutls-openssl27 is installed in version 2.12.23-12ubuntu2.1 (which is vulnerable) but I have 3.2.16-1ubuntu2.1 installed instead.

May it be related to Use of uninitialized value $package in hash element at ./lpvs-scan.pl line 302.?
