Definition:
For each buildenv, test builds are continually run on a set of dedicated machines known as the pointyhat cluster, after the name of the machine that dispatches the jobs.
For maintained ports:
Unmaintained ports, or ports the maintainer does not know how to fix, are marked with a special Makevar: BROKEN. BROKEN ports are neither built on the cluster nor installable (by default) by users (but they can override via 'make TRYBROKEN="yes" install')
BROKEN: fails to compile/install/deinstall correctly
IGNORE: incompatible for some reason (architecture, OS version, conflict with existing port)
