Can I install an older version of MacPorts to easily compile i386 only on Snow Leopard?

Thanks for your reply Ryan.

One mentions that build_arch is not reliable, and I tried adding the
universal variant and altering it to just i386. I also set compiler flag
environment variables, no joy. This was all with rebuilding all ports. I
guess the one option I haven't tried is building universal with both 32 and
64 bit.

I didn't encounter any problems in addition to the ones reported in the
links above.

I assume removing all installed ports and rebuilding everything works for
this, right? I'm going to be starting over again, so it's really no loss.
