Error with the update from version 2.2.1 to 2.3.3

[benjii.lac@…]

I installed Macports one year ago. I need library in order to run FreeFem on my MacBook.

It appears that I need to update it so I used the command sudo port selfupdate An error pops up and I didn't succeed to solve it. I precise that I'm new on computer science. I've few knowledges but not enough to understand everything yet.

So I took a look in the difference tickets (for example Ticket #46193) and try the command sudo port -v selfupdate and I got this :

Have you an idea of what is going wrong?

It sounds like you have not installed the Xcode command line tools.
