emcws (emacs) をportsから入れようと思っているのですがいかの
エラーメッセージが出て駄目です。

===> Installing for Xaw3d-1.5
===> Generating temporary packing list
===> Checking if x11-toolkits/Xaw3d already installed
===> Xaw3d-1.5 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 x11-toolkits/Xaw3d
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/x11-toolkits/Xaw3d.
