Hello when i run evilgrade i get this. I am running Kali linux 2.0 mini.

Base class package "isrcore::Shell" is empty.
(Perhaps you need to 'use' the module which defines that package first,
or make that module available in @inc (@inc contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.22.2 /usr/local/share/perl/5.22.2 /usr/lib/x86_64-linux-gnu/perl5/5.22 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.22 /usr/share/perl/5.22 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base .).
