Remove dev-perl/Regexp-Common (in ::perl)
Remove net-misc/openvpn

Uses its own protocol, not supported by other clients or OSes.
I'll most likely never use it.
Remove media-libs/libcaca

Was used for some long-forgotten SSH experiment.
We'll miss you, infantile scatology.
Remove net-wireless/hostapd

It only supports a small number of chipsets with dodgy drivers.

Pity.
