bsd.compile.mk

[Gary Aitken]

My apologies if this shows up twice;
tried to send it before without this addr subscribed.

In trying to rebuild ports,
UPDATE indicates my Nvidia driver has to be rebuilt.
9.2 release, amd64

The driver is proprietary and downloaded outside of the
ports tree.

When I attempt to build it, I get the following:

"/sys/conf/kmod.mk"  line 76:  Could not find bsd.compile.mk

/usr/share/mk does not have a bsd.compile.mk
where is it supposed to be and how is it supposed to get there?

Thanks,

Gary
