upgrade error

[somae7]

I got the following error trying to use "porti[grade -a" following the 
UPGRADING file (section for xorg). The error message says to remove 
files using pkg_delete but it isn't clear to me which files or how to do it.

===>  Installing for kdelibs-3.5.7

===>  kdelibs-3.5.7 conflicts with installed package(s):
     kdebase-3.4.2_2

     They install files into the same place.
     Please remove them first with pkg_delete(1).
