In the future, please use WikiFormatting, fill in the Port field and Cc the port maintainer(s) (port info --maintainers py27-goocanvas), if any.

You have provided no useful information to debug your problem. Please attach the main.log file after cleaning the port (sudo port clean py27-goocanvas) and re-open the ticket.

However, I'm guessing the problem is the one listed in the output you provided. Namely:

Warning: xcodebuild exists but failed to execute
Warning: Xcode does not appear to be installed; most ports will likely fail to build.
