Perl::MinimumVersion takes Perl source code and calculates the minimum version of perl required to be able to run it. Because it is based on PPI, it can do this without having to actually load the code. Currently it tests both the syntax of your code, and the use of explicit version dependencies such as require 5.005.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
