pkg_deinstall won't remove ports that are required by other ports. 
pkg_deinstalling a Perl (p5-) port, for example, won't forcefully 
deinstall lang/perl itself (unless you're removing the very last port 
that requires lang/perl).  'man pkg_deinstall' will tell you how to 
accomplish what you want.  There are a number of other port mgmt 
utilities as well.  (sysutils/portmaster comes to mind.)

Good luck!
