Note:

BROKEN_* and IGNORE_* can be any generic variables, for example, IGNORE_amd64, BROKEN_FreeBSD_10, etc. With the exception of variables that depend on a USES, place those in Section 15.8, “USES and USE_x”. For instance, IGNORE_WITH_PHP only works if USES=php is set, and BROKEN_SSL only if USES=ssl is set.

If the port is marked BROKEN when some conditions are met, and such conditions can only be tested after including bsd.port.options.mk or bsd.port.pre.mk, then those variables should be set later, in Section 15.11, “The Rest of the Variables”.
