This should be possible (the universal Leopard SDK is certainly part of Snow Leopard's Xcode), but is not something MacPorts was designed to do and is not tested so it might not actually work properly.

What I meant is that if you install something via macports with dependancies (libs the software depends on) these need to be either included in the binary or you need to install the dependancies via macports on the target as well. I don't know if smartmontools HAS dependancies thiugh and am not on my mac to check.

Hmm, can't look right now but also can't vouch for it.
But the xcode for leopard should be availlable. I think 3.2.6 is only for snow leopard.
