Where do I put options to ports make directives?

[stan]

I'm rebuilding a machine that suffred a root disk crash. I can't seem to
find the place to put the optiosn I pass to various port's "make install"
comands (as defines), so they will be reused, when I use portupgrade to
keep them up to date.

Where is thsi file?
