OpenBSD ports(7) -- get ports source, cd to package dir, then
# make patch
then, substituting <pkgname> suitably
# ( cd /usr/ports/pobj/<pkgname>/<pkgname> && patch -p 1 < $PATCHFILE )
then, if patch applied cleanly[*]
# make update
[*
else get source from ISC, extract, cd <pkgdir>,
# patch -p 1 < $PATCHFILE
then edit
bind/bind-9.9.5/lib/isc/random.c
and comment out line
'arc4random_addrandom((u_char *) &seed, sizeof(isc_uint32_t));'
then preferably configure with install --prefix other than /usr/local.
# make && make install
