changing configure options when using a port

[August Simonelli]

Hi all,

I'm slowly getting used to FreeBSD from a Linux background so forgive 
the ignorant questions.

I'm curious what the best way to add configure options are when 
installing from a port. For example, i'd like to add --enable-rewrite 
to apache2. Can I just put it in the Makefile in /usr/ports/www/apache2 
? Is this generally the best way to do this?

Thanks in advance,

August
