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/apache20
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/apache20.
