Error: port uninstall failed: too many nested evaluations (infinite loop?)

Question

I'm trying to uninstall MacPorts, following the instructions at MacPorts Manual.

But there is a cyclical dependency, related to python26, X and tk. The is my port list:

How can I get rid of MacPorts?

Answer 1

Ignore the --follow-dependents option and just use:

sudo port -fp uninstall installed

Then proceed with the second step.

Even if the first step fails, the following rm should delete all the files installed by MacPorts. It usually installs all files into /opt/local, except for a few files that have to be in a specific directory, such as the startup files in /Library/LaunchDaemons and the application bundles in /Applications/MacPorts.
