Installed MacPorts packages sizes

You could make use of port build in command contents, which gives you the oportunity to do things like that:

port contents --size depof:python27

Grep the lines you need and do the maths :-)

Update: found answer here at guide.macports.

While reading a bit deeper, I found this

port space --units MB --total thisport

which is much more handy then calculating the sum of the size of each file inside a port.

Using the command:

du -sh /opt/local/var/macports/software/*

echos back all directories and sizes of your installed ports.

Use the command:

port -d echo installed

echoes a listing of the ports installed.

To get each port along with a total of all ports just type port space installed
