Failed to activate py27-matplotlib

[caverac]

Hi there!

I've been trying to upgrade macports and get this message at the end

---> Found 8 broken files, matching files to ports
---> Found 3 broken ports, determining rebuild order
You can always run 'port rev-upgrade' again to fix errors.
The following ports will be rebuilt:

py27-matplotlib-basemap @1.0.7
sumo @0.27.1+messages+subseconds
webkit-gtk @2.4.11+video

Continue? [Y/n]: Y

This is what I get

I don't know what to do with this, any suggestion will be really appreciated. Thanks in advance
