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
.
