No.

BTW. The library location is os.path.join(sys.prefix, 'lib', 'python%d. 
%d'%(sys.version_info[:2])).  This should resolve to a path that  
doesn't refer to 'Versions/Current' but to 'Versions/x.y'.  Do not  
assume that the 'Current' link will point to   currently running  
version of Python, a user might have installed multiple versions of  
python.
