Problems Installing PyQt on OS X 10.6.3

I am trying to install PyQt on a Mac equiped with OSX 10.6.3.  I have the mac developer tools loaded and seemed to install Qt and the sip packages without a problem but I keep getting link errors when I try to compile PyQt.  Below is the output from (I believe) the start of the errors:

I have installed:
qt-mac-cocoa-opensource-4.6.3.dmg
sip-4.10.2 (compile and install)
and am trying to compile and install PyQt-mac-gpl-4.7.3.  

Any suggestions on how to get this working?
