Log::Message is a generic message storage mechanism. It allows you to store messages on a stack -- either shared or private -- and assign meta-data to it. Some meta-data will automatically be added for you, like a timestamp and a stack trace, but some can be filled in by the user, like a tag by which to identify it or group it, and a level at which to handle the message (for example, log it, or die with it) Log::Message also provides a powerful way of searching through items by regexes on messages, tags and level.
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.
