[PyQt] Unable to compile PyQt on 10.5.1 (fails while linking)

Hello all,

	I'm new to the list and found it when I encountered problems trying  
compile PyQT on my Powerbook G4. I'm running a fresh copy of 10.5 then  
upgraded to 10.5.1. As this thread indicates:

http://www.mail-archive.com/pyqt@riverbankcomputing.com/msg12139.html

I looked into the symlink mentioned, but apparently it's already set  
up - although curiously backwards from what the about thread indicates.

I've re-compiled QT, but I still get the below error, also this only  
happens when compiling the OpenGL module not when compiling any other  
PyQT module (say QtSvg or QtSql).

To make life more interesting, some of the OpenGL examples provided  
with QT don't compile in Xcode. For example the hellogl application  
does compile but the framebufferobject and framebufferobject2  
applications do not.

So I imagine I've found a problem with how QT has set up it's linker  
preferences, and being that I'm new to both QT and how OSX utilizes  
Frameworks I  thought I'd ask the experts, and see if there were any  
wise words that could be shared with me.

Cheers,
Brian
