If your port needs to determine if it should install or not, you
can create a pkg-req
“requirements”
script. It will be invoked automatically at
installation/de-installation time to determine whether or not
installation/de-installation should proceed.
The script will be run at installation time by
pkg_add(1) as
pkg-req ${PKGNAME} INSTALL
.
At de-installation time it will be run by
pkg_delete(1) as
pkg-req ${PKGNAME} DEINSTALL
.
