Universal Binaries

[Timothy Lee]

I just compile 1.7.0 from source and my macports.conf universal_target  
has a 10.4 next to it. However, when I compile on my Leopard machine,  
I see DEBUG: Environment: MACOSX_DEPLOYMENT_TARGET='10.5'.

I thought universal_targe would set the MACOSX_DEPLOYMENT_TARGET.

Am I wrong?
