Apply by doing:

Apply by doing:
cd /usr/src
patch -p0 < 004_httpd.patch

And then rebuild and install httpd and its modules:
cd usr.sbin/httpd
make -f Makefile.bsd-wrapper obj
make -f Makefile.bsd-wrapper cleandir
make -f Makefile.bsd-wrapper depend
make -f Makefile.bsd-wrapper
make -f Makefile.bsd-wrapper install

If httpd had been started, you might want to run
apachectl stop
before running "make install", and
apachectl start
afterwards.
