The great thing about pkgsrc is that there are a couple thousand examples!

Also, the documentation at pkgsrc/Packages.txt is very useful and
frequently improved.

Have a look at an up-to-date Packages.txt and read about PLIST_SUBST.

Then search a few categories Makefiles and find some examples, like:
graphics/gdk-pixbuf
sysutils/grub

Basically you have a variable in your PLIST. If you want that entry to
really exist the variable is blank. If you want it to not exist, that
variable becomes a comment.
