Note that sudo port install python27 did not "fail". It correctly reported that python27 was already installed. Then, rev-upgrade automatically ran, as it does after every install or upgrade, to see if anything was broken, and it correctly reported that your python27 installation is broken because some files are inexplicably missing. So try reinstalling python27, by running:

sudo port -n upgrade --force python27
