SIP is a tool that makes it very easy to create Python bindings for C++ libraries. It was originally developed to create PyQt, the Python bindings for the Qt toolkit, but can be used to create bindings for any C++ library. Sip 5.* is in build-time usage totally incompatible with sip 4.*. It is the last version that supports API/ABI version 12.7, which is the version used by sip 4.* in pkgsrc, and by PyQt5. So bindings generated by sip 4.* and sip 5.* can cooperate, but not 4.* with 6.*.
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.
