[Qgis-developer] Building universal binary on Leopard for Tiger

[Gary Sherman]

Mac gurus,
I'm trying to build a universal binary for QGIS that will run on both  
Leopard and Tiger. If I build using the 10.5 SDK it doesn't run on  
Tiger. If I attempt to build using the 10.4 SDK, the build fails with:

I've passed -mmacosx-version-min=10.4  as a CXX flag during the  
configuration process.

Ideas?
