Thanks for catching. Fixed in v2.

It doesn't appear that there's an option to only build the SMP
version. It looks like if you manually delete the UP version, Erlang
still works fine on an SMP system. I must admit, though, that I don't
know if this will always work and I'm a little uneasy about doing it
without more testing.
