I am wondering if this is lack of support of Macports for py27-pygraphviz py27-goocanvas py27-kiwi or is it because of Xcode being missing and using only command line

This is the log after cleaning as suggested earlier.

166:~ mohibihussain$ sudo port clean py27-goocanvas

Do you have Xcode and the command line tools installed for 10.11.6?

1. Install Xcode
2. Install the command line tools
3. Run sudo port clean py27-goocanvas
4. Retry what you were originally doing

If it fails again, please attach the main.log file.
