In addition to that which others posted in response....

You could try
   # cd /usr/ports/<port-of-choice>
   # make pretty-print-run-depends-list
       - or -
   # make pretty-print-build-depends-list

You can do these *before* you install a port to see what the impact will 
be.  Or at any date afterwards to see what is/was required by the port.
