FreeBSD ports which are currently marked forbidden

[linimon at FreeBSD.org]

As part of an ongoing effort to reduce the number of problems in the
FreeBSD ports system, we periodically notify users about
ports that are marked as "forbidden" in their Makefiles.  Often,
these ports are so marked due to security concerns, such as known
exploits.

An overview of each port, including errors seen on the build farm,
is included below.
