Doing it within a 32bit chroot (or jail) is probably the
easiest way. At least it was for me. I simply took a
32bit install from an FTP mirror, installed it into
/usr/i386, mounted devfs inside it (and mdfs on tmp),
then chrooted into it, and everything worked as expected.
Of course, if you have a 32bit world on some other box,
you can simply make a copy of it for your chroot.

Of course, be sure that your amd64 kernel contains the
line "options COMPAT_IA32" (it's in GENERIC by default),
so the i386 binary compatibility is enabled. You also
have to make a link inside the chroot's /libexec:
# cd libexec
# ln ld-elf.so.1 ld-elf32.so.1

And finally, certain Makefiles (including our buildworld
target) will be confused and think that you're attempting
to cross-compile. In order to trick them into assuming
that you're running on a 32bit kernel, you have to set
these environment variables before:
# export UNAME_m=i386
# export UNAME_p=i386
If you're using csh or tcsh, use this syntax instead:
% setenv UNAME_m i386
% setenv UNAME_p i386

With the above settings, I was able to perform a full
buildworld + installworld within a 32bit chroot on a
64bit host. The result was still a 32bit world, of
course.

Best regards
Oliver
