Thanks, I couldn't get that to work with configure.macosx_deployment_target variable, it seemed as if MacPorts does not know that variable, and judging from the MacPorts 1.6.0 changelog, that variable was indeed removed.
Adding -mmacosx-version-min=10.4 to the compiler AND linker flags did the trick, though. Many thanks for pointing the way!!!
It did build and install, now I only need to test how my static building of Exult fares :)
