Comment (by mioose@…):

 Hello, thank you for your answer. Now, I think I have a problem linked
 with 10.11 El Capitan.
 I obtain this error :
 " Error: python25 is not supported on Yosemite or later.
 Error: org.macports.fetch for port python25 returned: unsupported platform
 Error: Failed to install python25 "

 I have tried to reinstall as they advice here:
 http://stackoverflow.com/questions/27873045/port-upgrade-outdated-fails-
 in-yosemite but I obtain the same error.

 Others dependencies have to be installed too: "Error: The following
 dependencies were not installed: python25 tk Xft2 tcl xorg-libXScrnSaver
 xorg-scrnsaverproto"
