unable to load object bundle executable

Hello list.

This is an error that is cropping up on my relatively new mcb i7 late 2010, osx 10.6.8. This has happened when trying to use various externals included are the error messages from the two most recent failures.

So I see in the list archives that this error is something that pops up from time to time for people, but what does it refer to? Is there any steps I can take in order to close in on the problem that prevents these externals from working. ?

Thank you
