Fixed in v2. > Is there an option on only build (or at least install) the SMP version? 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. Frank
