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.

I've install on January, 29 2015 the version 6.1 via App Store of Command Line Tools (OS X 10.9). I'm still running OS X Maverick. Do I have to install another plug in for Xcode?

I read this file, and I discovered that I didn't accept the agreements of xcode. So I type "sudo xcodebuild -license" and agree to them Then I type another "sudo port selfupdate" and it worked.

But then an issue appears :

mbp-de-benjamin:~ Benjamin$ sudo port selfupdate

The ports tree has been updated. To upgrade your installed ports, you should run
  port upgrade outdated
mbp-de-benjamin:~ Benjamin$ port upgrade outdated
Error: Insufficient privileges to write to MacPorts install prefix.

How do we get privileges to write to MacPorts ?

You need admin privileges for that too.

$ sudo port upgrade outdated
