Any software installed by MacPorts or compiled by hand could find  
libraries in /usr/local without notice. In the case of MacPorts- 
installed software, this would most likely interfere with the ability  
of MacPorts to manage your dependencies in a reliable manner. As I  
said above, it is not supported to have anything in /usr/local while  
using MacPorts. That means you can do it if you want, but if you  
encounter problems we will not support you in making MacPorts work  
with that setup; we will tell you to get rid of what's in /usr/local  
and try again.

MacPorts will not install things in /usr/local so I can't think why  
there would be any clash when copying things back there. Also don't  
think you need to copy anything; simply moving the directory would be
