making packages from ports

[Dave]

Hello,
    I've got a box i'd like to build packages from ports on, and deploy 
those packages to other machines. I'll use postfix as an example. I did make 
package from postfix's directory and selected pcre and mysql support. I got 
the postfix tarball package, but when i tried to install it on another box 
it needed pcre and mysql-client packages. I had to run make package in each 
of their directories. I was wondering if there was a recursive way of 
package making?
Thanks.
Dave.
