mplayer and x11 libs

[Dave]

Hello,
    I've installed the mplayer port previously i used the WITHOUT_X11 option 
because i didn't want x11 support as well as didn't want gtk2 and the libs 
it brings in. Yet, a porgupgrade of this box pulled in those libs. I've 
corrected this by uninstalling mplayer and it's dependencies with 
pkg_cutleaves and reinstalling. How do i prevent this in the future?
Thanks.
Dave.
