UPD: I finally built it after using 10.5 SDK and target with:

macosx_deployment_target 10.5
macosx_sdk_version 10.5

Probably should build if -isysroot/Developer/SDKs/MacOSX10.5.sdk is added to CFLAGS and CXXFLAGS in port file (instead of changing Macports global settings).

Ok great, then do that.

You're supposed to be able to build for older systems (setting macosx_deployment_target to the oldest version you want to run on) even while using the latest sdk, but that didn't always work correctly back in these early days of sdks, so sometimes using the sdk for the oldest version is better (though of course it means what you build will not be able to use features introduced in newer sdks).

Indeed, I could try changing deployment target first and resort to changing SDK if the first fails. Thank you.
