>Description:
Running "make checksum" in a port that has conflicts with another port that is already installed fails.

Example.
centel# make checksum

===>  firefox-3.6,1 conflicts with installed package(s): 
      firefox-3.5.7_1,1

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

Stop in /usr/ports/www/firefox.

This has happened in a number of ports that I don't have a list for any more.

This type of activity also prevents upgrade tools from working in ways of just fetching updates using the "checksum" method to ensure that a port has downloaded properly instead of using "make fetch".
>How-To-Repeat:
Pick any installed program from ports that has a conflict with another package and run "make checksum" in one of its conflicts.
>Fix:
I have not researched this further. A fix should be based around not checking for conflicts during any other method than just "make".
