Easiest approach to avoid that part seems to be seting up a full i386
jail inside the amd64 host, and install WINE normally from the ports.

>From man jail(8):

  host# D=/here/is/the/jail
  host# cd /usr/src
  host# mkdir -p $D
  host# make world DESTDIR=$D
  host# make distribution DESTDIR=$D
  host# mount -t devfs devfs $D/dev

But as suggested here <http://en.jnlin.org/2008/06/07/12/> I actually:

  host# make world distribution TARGET_ARCH=i386 TARGET=i386 DESTDIR=$D
  host# ln -s ld-elf.so.1 $D/libexec/ld-elf32.so.1

Then added IP alias for jail use, set up a unionfs over ports (to avoid
having them double) and can correctly login in the jail:

  host# ifconfig em0 inet $IP/32 alias
  host# mount -t unionfs -o noatime,below /usr/ports $D/usr/ports
  host# jail $D $HOSTNAME $IP /bin/tcsh

>From there I normally installed WINE:

  jail# cd /usr/ports/emulatos/wine
  jail# make install clean

…but then it just “bus error” dumps on me… something to do with LDT:

  jail# winecfg
  Bus error (core dumped)
  jail# gdb `which wine-pthread` wine-pthread.core
