removing base software

[Tom]

hi all,

how do i remove base system software safely?  i did the minimal installation 
with man pages ( and no more ).  my server does not need sendmail, telnet and 
the printing system.  since i have read the handbook, i know that these are 
not ports and do not fall under the pkg_* utilities.  so, how do i remove 
them ( or prevent them from getting installed in the first place )?

thanks,

tom
