But you cannot define any OPTIONS_* variables after including
bsd.port.options.mk (which happen about in the middle of what
bsd.port.pre.mk does.)


The thing that people who want to do something like this usually do is
an ugly:


OPTIONS_DEFAULT= FOO BAR ${OPTIONS_DEFAULT_${OPSYS}_${OSREL:R}}
OPTIONS_DEFAULT_FreeBSD_10= BAZ


It is usually a bad idea, why are you trying to do this ?
