[Pyobjc-dev] Reprise: Import error: Bundle could not be loaded

[Mike R. <ros...@fr...>]

For the benefit of future archive searchers, I will summarize the  
solution I stumbled on to regarding the "Import error: Bundle could  
not be loaded" problem I was experiencing with loading up my own  
framework in PyObjC.

Scenario: Attempting to build a simple python test harness to perform  
unit tests on a custom framework.

Problem: The following code generates the error "Import error: Bundle  
could not be loaded".

  	import sys
	import objc
	fubarBundle = objc.loadBundle("Fubar", globals(),  
bundle_path=u'the_path_to/Fubar.framework')

Cause: The Fubar.framework references another custom framework which  
could not be located.

Solution: Fubar.framework wants alice.framework.  So I dropped a copy  
of alice.framework into /Library/Frameworks/ and the above code  
worked properly and I was able to exercise the Fubar framework.  (~/ 
Library/Frameworks/ worked as well.)

Analysis: Performing a loadBundle in the test harness python code on  
alice.framework successfully loaded alice but did not make it visible  
to Fubar.  Neither did an NSBundle.bundleWithPath followed with a load.

The disadvantage of the above solution is that it requires  
potentially unstable frameworks to be loaded into a system-visible  
location.  (There's probably some other way to make alice visible  
within this process and I would surely like to hear about it.)
