I'm still trying to get py2app to work for our BioImageXD software,

It appears to be the case that py2app is NOT re writing the  
install_name of included non system .dylibs
(like the intel libguide and the vtk libs I am using)
as you suggest it should be doing,
so that they have

@executable_path/../Frameworks/libWhatever.dylib

instead of just

libWhatever.dylib

as their install_name, as can be seen by
otool -L

So now I wonder if this "should" be happening as the py2app code  
stands as you imply above, but isnt happeneing due to a problem,

or

if it is not happening since this is not what py2app is trying to do.

Has it been fixed in a recent development version,
or is it really broken in my case,
or does that functionality need to be added?

cheers
