Yes, it is a required variable.

Just list "darwin". It has become the de-facto default.

The idea behind this variable was to support multiple target platforms, but
while we keep MacPorts base running on Linux for server-side tasks, almost none
of the ports work there and it is completely unsupported. Additionally,
puredarwin is dead, so there's not point in considering it either.

We often use a platform darwin {} block when adding conditional code depending
on a version of OS X, but that's mostly to keep our Linux servers happy when
they are generating the PortIndex.
