In case you missed the announcement in May:
http://lists.freebsd.org/pipermail/freebsd-ports-announce/2014-May/000080.html
In short, any ports that have not been yet converted to use the now mandatory staging mechanism have been marked as deprecated and their maintainers have been reset. This could affect you if you build your own packages from ports, those ports will still build but you will get a warning about the deprecation. Eventually these ports will be marked broken and deleted unless updated to use staging. The number of ports as of today that are not yet converted to staging is about 1600 out of the 24000+ ports.
