12.2 pkg-install

If your port needs to execute commands when the binary package is installed with pkg_add you can do this via the pkg-install script. This script will automatically be added to the package, and will be run twice by pkg_add. The first time as ${SH} pkg-install ${PKGNAME} PRE-INSTALL and the second time as ${SH} pkg-install ${PKGNAME} POST-INSTALL. $2 can be tested to determine which mode the script is being run in. The PKG_PREFIX environmental variable will be set to the package installation directory. See pkg_add(1) for additional information.
