I just realized that one reason my scripts won't work for you is that 
dylibs_isdylib() uses the file suffix to determine if a file is a library.  
Something more robust should probably be done, but at the minimum the ".so" 
suffix would need to be included. 

Even so, that doesn't explain why the install_name_tool commands executed via 
Octave didn't to the job correctly.
