 The default value for MACOSX_DEPLOYMENT_TARGET is 10.1 on Mac OS X 10.4
 and earlier, and 10.5 on Mac OS X 10.5.

 MacPorts trunk includes code to set MACOSX_DEPLOYMENT_TARGET to the same
 value as the version of Mac OS X, but MacPorts 1.6.0 does not contain that
 code. So until MacPorts 1.7.0 is released you should apply the attached
 patch to the portfile.
