A bit of a minor problem with Qt 4.4 on OSX, that I haven't seen with  
previous versions of Qt: when embedding the Qt frameworks, I reset the  
install_names of the interlinked Qt frameworks to relative paths (Tom  
does this with his also).

Now with Qt 4.4, this finds the Qt plugins in /Developer/Applications/ 
Qt/plugins, if they are installed (I don't include the Qt plugins in  
my package).  These plugins still have their install_names set to find  
the installed Qt frameworks, which then causes confusion in the linker  
and Qgis crashes on startup with (the first few lines of the trace):

Exception Type:  EXC_BAD_ACCESS (SIGBUS)
Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000010

Thread 0 Crashed:
0   libqtaccessiblewidgets.dylib  	0x157be6f7  
QAccessibleScrollBar::childCount() const + 17
1   QtGui                         	0x00eadbca  
QAccessible::updateAccessibility(QObject*, int, QAccessible::Event) +  
2   QtGui                         	0x00a13054  
QWidgetPrivate::show_helper() + 420

This does not happen when the Qt frameworks are not embedded.   
Embedding the Qt plugins doesn't help, if they are still also in / 

Is there some way for Qgis to force Qt to NOT load plugins from / 
Developer?  Otherwise I must put a warning in the readme about this,  
with a recommendation to move/delete the /Developer Qt plugins.
