And I didn't upgrade because i have a really slow internet connection for now, software update cant even "find new software" for example today "network issues" even if the rest of internet is working. I'm also using my personal laptop work too. So I prefere upgrading when I'll be sure to have time to fix things if they are broken by an update. -- Ticket URL: <https://trac.macports.org/ticket/31466#comment:5> MacPorts <http://www.macports.org/> Ports system for Mac OS

The `qt4` variant provides the `qt4` and `qt4agg` backends, you're trying to use `qt` which is the backend based on QT3, hence it's not found. -- Ticket URL: <https://trac.macports.org/ticket/31466#comment:8> MacPorts <http://www.macports.org/> Ports system for Mac OS

So maybe the message must be more explit like "this Qt backend requires pyqt3 to be installed." but his is more a matplotlib upstream issues i think. And maybe Matplotlib example should be updated to also make use of Qt4 .

The QT3 python bindings are called pyqt, so it's reporting that the appropriate module is missing. -- Ticket URL: <https://trac.macports.org/ticket/31466#comment:10> MacPorts <http://www.macports.org/> Ports system for Mac OS
