Good news.

You can use any available version of XCode tools including the latest
3.2.2.  Defaulting to the oldest means the later APIs are absent and
better tests compatibility.

I was of the opinion that Apple provided the old SDKs just for this very
purpose.  Why doesn't the current packager leverage this facility?

One last update includes command line switching between 10.4, 10.5 and

mkodcctools -4 => 10.4
mkodcctools -5 => 10.5
mkodcctools -6 => 10.6

Also added parallel make of gcc.  This version also supports later Apple
gcc's (upto gcc5493).  No gcc 4.2.1 yet, but I'm working on it.  

New script & patches (for Qt with 10.6) available from here:
