He's on an Intel Snow Leopard machine, and wants to compile smartmontools for a PowerPC Leopard machine. 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.

Nothing installed by MacPorts links with any part of MacPorts itself, so certainly installing MacPorts itself on the target would not be necessary. And Xcode is only needed to compile the software; once it's compiled, that's no longer needed.

I was unable to find a standalone (iOS-less) Xcode 3.2.6 installer; is there one? I know there was for earlier 3.2.x releases.


Chris, give me a minute and I can boot up my PowerPC Leopard machine and make you a binary installer package of smartmontools.
