FreeBSD で wine wow64 がやりたいと思って以下のことをしました。
64bit# tar -xvpf "somewhere lib32.txz" -C /
64bit# mkdir -p /compat/i386
64bit# tar -xvpf "somewhare i386 base.txz" -C /compat/i386
64bit# mount -t devfs devfs /compat/i386/dev
64bit# mount -t nullfs /usr/ports /compat/i386/usr/ports
64bit# pkg install wine flex bison gmake binutils xorgproto pkgconf
64bit# pkg delete wine
64bit# cd /usr/ports/emulators/wine && make
64bit# mv work work.wine64
64bit# chroot /compat/i386 /bin/sh
32bit# service ldconfig start
32bit# pkg install wine flex bison gmake binutils xorgproto pkgconf
32bit# pkg delete wine
32bit# cd /usr/ports/emulators/wine && make
32bit# mv work work.wine32-tools
32bit# env CONFIGURE_ARGS="--with-wine64=../../work.wine64/wine-5.0 --with-wine-tools=../../work.wine32-tools/wine-5.0" make
32bit# mv work work.wine32
32bit# exit
64bit# mkdir -p work/stage/compat/i386
64bit# cp -a work.wine64/.??* work/
64bit# cp -a work.wine32/stage/usr work/stage/compat/i386/usr
64bit# cp -a work.wine64/stage/usr work/stage/usr
64bit# cd work/stage && find . -type l -or -type f | sed -e 's/^\.//' > ../.PLIST.mktmp
64bit# make install package
64bit# echo /usr/local/lib /compat/i386/usr/local/lib >> /etc/libmap32.conf
