Somewhere the original note never made it to my inbox.

For the carbon mac vm, the code to load the framework is now in 
sqMacExternalPrims.c The function is LoadFrameworkBundle, which is 
code taken from an Apple example. This code does a find folder on 
kFrameworksFolderType and proceeds from there to find the framework.

People who build plugins etc should take note, 99% of the plugin not

resolve plugins/frameworks.

But it seems it's not quite what you want.

I'm just about to issue 3.2.5, so this is go into 3.2.6. If Mr. 
Fischer can email me then I'll send him an early copy to test once I 
figure out what to do, now I wonder if it's
