2 weeks later:

I've submitted to the MacPorts project all of the fixes needed to get  
the Python 2.5 and related ports (e.g. wxPython) up and running on  
both MacOS X 10.4 and 10.5.  Most of the ports work "out of the box"  
on 10.4 and 10.5 now, but Python is one of the remaining holdouts  
mostly due to conflicts in the dynamic library crowd versus the  
framework crowd (which is inherently dynamic, just in its own install  
space).  Once those fixes are in place, my 10.4 install script should  
work just as it is ... with the same issues as before (e.g. SDCC from  
MacPorts won't work on Intel Macs; download and install the pre- 
compiled one).

I still can't get GNU Radio's WX GUI stuff to work using GNU Radio's  
scripts.  OTOH, using the demo scripts I wrote over the summer,  
including a partial "framework" for doing GNU Radio applications, I  
can get pretty much everything working on 10.5 just as it does under  
10.4.  The primary difference, I think, between my framework and the  
GNU Radio examples is that the latter uses the new "top_block", while  
the former uses "flow_graph" .. yes, I know I need to update - I just  
hesitate to fix what ain't broke until I need to :)

Anyway, we've experienced this issue before with the spectrum_sense  
code - "flow_graph" version works while the "top_block" one hangs ...  
but in this case the issue was fixed by moving from Python 2.4 to  
2.5.  Now I find a similar issue when running on MacOS X 10.5 versus  
10.4, both under Python 2.5.  'Tis a mystery.

I will continue to investigate this issue; more later. - MLD
