Error activating expat while Installing Gwyddion for the 1st time

[havefun@…]

Hi, I'm using MacPorts for the first time. Its installation went well and I can execute minor commands like "installed" etc... However, I get this error message after typing the install command for gwyddion. any ideas? I do not get along with that...

thanks!

ps

the command "port -f activate expat" does not work:
