[Qgis-developer] QGIS Python support in a library

[William Kyngesburye]

I've been busy and tired all week, and just got a chance to try it.

So far I can confirm I'm also having the python non-start problem.   
 From your otool lists, I wonder if it's the @executable_path?  In my  
test I didn't do my whole packaging routine, where I change those to  
@loader_path.

The problem I'm guessing is with @executable_path, that there may be a  
confusion as to what is the "executable" when the python support is  
started - python or qgis?  If it's python, then it'll fail to find  
anything inside the Qgis app bundle.

But your all-in-one Qgis builds have worked in the past with  
@executable_path, and I don't realy know much about how python support  
is loaded in Qgis, so I'm probably just overanalyzing it ;)

I'm working on some build updates this weekend, so I should be able to  
do a more thorough build test soon.
