Definetely wrong, its APACHE_PORT=www/apacheXX
I'm guessing you are looking for something similiar to:

.ifdef USE_MYSQL
.error You have `USE_MYSQL' variable defined either in environment or in 
make(1)
  arguments. Please undefine and try again.
.endif

It might be more complicated than that since we ship with an executable 
that merely prints out a message to go install perl.

We'd actually have to parse the output
