[Pythonmac-SIG] pyObjC and Plugins

[Dethe Elza]

Hi Steve,

My first thought was to make sure that you were getting the python  
you just build when you type "python" at the command-line.  I've had  
problems like this before when I had the wrong python in my Path.

Then I thought, what if the problem is with the example code?  I know  
I've built that example in the past--I have it running and just used  
the code yesterday to figure out how to set environmental variables  
globally in OS X for a friend.  So I tried building and installing  
it, and I got the same problem you did.  I haven't had a chance to  
pore over the log files or svn blame yet, but I would recommend a)  
trying a different example, and b) looking through the svn history to  
see what has changed recently in the EnvironmentalPrefs code.

The only really recent change was when Ronald added a bundle  
identifier, but reverting to an version before that has the same  
problem so the change must be earlier.  I have to get the kids (and  
myself) ready for the day, but I'll check in later if I figure  
anything else out.

It's like I'm living my own version of the Singularity. I both revel  
in it and am scared by it. I want to figure out how to crawl into a  
moment and expand it out so that I can fully experience it, but at  
the same time know that the rapid flow of events makes it's own  
experience.
