[Eric] Bus Error running eric's install.py at qVersion() call

[Curtis Faith]

I'm having one hell of a time installing Eric4 on a brand new Intel  
MacBook running OS X 10.4.10

This is my fourth failed attempt at installing eric in the last year,  
and the first one on a Unix-based OS. If I can't get this to work  
soon, I will pick another IDE, I have spent about a solid day on this  
on this go around and am stuck on what should be the last easy step.

I have everything installed except the last step, and I have double- 
checked the order three times. I installed the latest versions of  
everything including:

Python-2.5.1
qt-mac-opensource-4.3.0
sip-4.6
PyQt-mac-gpl-4.2
QScintilla-1.73-gpl-2.1


The command:


sudo python install.py



results in:


Bus Error


I installed a new version of Python 2.5.1 and modified it to include  
the debugging symbols and tried running gdb and get:


curtis-faiths-computer:~/Desktop/eric4-4.0.0 curtis$ gdb python  
install.py

(gdb)

The bt command results in only the single entry for  
__dyld__dyld_start ()

This appears to be the call to dynamically load a shared library on  
Darwin as best I can tell.

I placed print statements inside install.py to find out that the  
following call:

	qtMajor = int(qVersion().split('.')[0])

is causing the Bus Error. Specifically the call to "qVersion()". This  
tells me that there is probably something wrong with the PyQt  
installation or SIP but I have no idea what it might be or how to  
proceed.

Does anyone have any idea how I can figure out what might be causing  
this problem?
