This is a bug which affects Leopard users in some circumstances. A  
workaround is already in MacPorts base in trunk. You can either build  
MacPorts trunk from source, or when you encounter the error, simply  
issue the "port upgrade" (or "port install") command again and it  
should work the second time.
