question on the firefox port...

[mojo fms]

I am having an odd problem on the firefox port. This is a fresh
install of Freebsd 6 and basicly what its doing ...

===>   Generating temporary packing list
===>  Checking if www/firefox already installed
===>   firefox-1.5_5,1 is already installed
      You may wish to ``make deinstall'' and install this port again
      by ``make reinstall'' to upgrade it properly.
      If you really wish to overwrite the old port of www/firefox
      without deleting it first, set the variable "FORCE_PKG_REGISTER"
      in your environment or the "make install" command line.
*** Error code 1

Stop in /usr/ports/www/firefox.
*** Error code 1

Stop in /usr/ports/www/firefox.

I have tried, make deinstall ; make reinstall same error. I am not
sure of what i should set FORCE_PKG_REGISTER to but i tried, YES,
www/firefox and NO for the settings on it. Running it like this :
FORCE_PKG_REGISTER="NO" make reinstall  ... i did this on make
reinstall and make install and nothing still..


make deinstall ...

root@# make deinstall
===>  Deinstalling for www/firefox
===>   firefox not installed, skipping
root@#

any suggestions please.

Thanks
