Hi,

is there a way to reliable detect that a package is getting built with
pkgsrc?
Sometimes you can detect the OS by testing for files like
/etc/redhat-release or using "uname" but since pkgsrc can be used on
many different systems this is not sufficient.

How about introducing ${LOCALBASE}/{etc,share}/.using_pkgsrc and defining an
environment variable like PKG_USING_PKGSRC during the package build?
