Visualization Interfaces for Large-Scale Displays

SCons is a "next generation" build tool written in Python. It is a make replacement, and much more. It will create PDFs from latex, compile C, C++, JAVA, MS Visual Studio Projects, and anything else you can think of. This would be a wonderful tool for cross-platform development, or development of a very heterogeneous system.

I can't seem to get glewpy to work under python2.5 on a PPC mac. 
 
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.5/lib/ 
python2.5/site-packages/glew/glew.so, 2): Symbol not found: _glewInit 
Referenced from: /Library/Frameworks/Python.framework/Versions/2.5/lib/ 
python2.5/site-packages/glew/glew.so 
Expected in: dynamic lookup 
 
Any idea why this symbol is not found in glew.so ?

The jittery mouse issue has been resolved. I did this by removing the send-thread from the client that sits on Visual. It seems that the communication between the two threads was not smooth, causing the mouse events to arrive at the cluster in bursts. It seems okay to keep multiple listen-threads.

This morning I revisited some C++ code which calls upon Python for some image manipulation. When I last touched this code it was segfaulting mysteriously. This morning it works. The only difference I can imagine is the jump to 10.4.3.

Is anyone familiar with SIP? There seem to be quite a few ways to wrap C/C++ code into Python. SWIG, SIP, Pyrex, and ctypes, to name a few.
