It's only loosely related to the number of libraries.  It's somewhat  
difficult to explain exactly why this error occurs, but it is  
normally quite rare and there isn't much that can be done about it  
from the py2app side of things.

The solution is to re-link the libraries that are having this problem  
with the -headerpad_max_install_names ld flag.  I think that there's  
some way to set LDFLAGS appropriately and then use port to rebuild  
them, but you'll have to ask someone else who knows more about the  
DarwinPorts toolchain because I have no idea.
