Well, no, it doesn't need to download gd. The php distribution  
already includes a version of gd, so that gets used.

If you look into the portfile (which you can see by typing "port edit  
php4") you'll see this section:

variant gd {
	depends_lib-append	port:jpeg port:libpng port:freetype
	
	configure.args-append	--with-gd \
				--with-jpeg-dir=${prefix} \
				--with-png-dir=${prefix} \
				--enable-gd-native-ttf \
				--with-freetype-dir=${prefix}
}

So you see that when you add the gd variant, it then makes sure the  
jpeg, libpng and freetype ports are installed. But no gd port is  
required.
