Sorry, once again I started writing email right after I woke up ...

What I described will show you upward and downward dependencies of 
installed packages, but not build dependencies. To do that, you can do 
this, using Firefox as an example (you don't have to be root to do 
this, but you do to deinstall a port):

% cd /usr/ports/www/firefox
% make pretty-print-run-depends-list
This port requires package(s) "atk-1.8.0 bitstream-vera-1.10 
expat-1.95.8 fontconfig-2.2.3,1 freetype2-2.1.7_4 gettext-0.14.1 
glib-2.4.8 gnomehier-1.0_22 gtk-2.4.14_2 hicolor-icon-theme-0.5 
jpeg-6b_3 lcms-1.14,1 libIDL-0.8.4 libXft-2.1.6 libiconv-1.9.2_1 
libmng-1.0.8 libxml2-2.6.17 pango-1.6.0 perl-5.8.5 pkgconfig-0.15.0_1 
png-1.2.8_1 shared-mime-info-0.15_7 tiff-3.7.1_2 
xorg-fonts-encodings-6.8.1 xorg-fonts-truetype-6.8.1 
xorg-libraries-6.8.1_1" to run.

% make pretty-print-build-depends-list
This port requires package(s) "atk-1.8.0 bitstream-vera-1.10 
expat-1.95.8 fontconfig-2.2.3,1 freetype2-2.1.7_4 gettext-0.14.1

xorg-fonts-truetype-6.8.1xorg-libraries-6.8.1_1 zip-2.3_2" to build.


As you can see, some of the packages are required to run and build, so 
you need those no matter what. Some of the other build dependencies, 
like zip, you probably would find useful otherwise, so you may want to 
keep something like that, too.
