Re: [graph-tool] installing graph tool on Mac OS X 10.8 by MacPorts

I closed the terminal window so I could run the port command again. This happened: MacBook-Air-de-Jaqueliny:~ JaquelinyLima$ sudo port install py27-graph-tool @2.2.27 Password: Waiting for lock on /opt/local/var/macports/registry/.registry.lock I have no idea on what does it mean.
