Confusingly this gets an answer that is readily misinterpreted, namely

In contrast

does not (inadvertently) deceive: it gives

I tried this and got:

So then I did

and got

This seems to me to indicate a bug in “port select —summary”. Firstly, it seems to answer incorrectly for inactive ports, like python27 in my case. I would have expected “port select —summary” to give python27 as an option. Secondly, it seems to incorrectly and indirectly imply that python26-apple and python27-apple are installed, which I think was your interpretation, but they aren’t installed, as I have checked with the “port installed” command.

It does feel as though I will, with the help of the list, be able to clean up my ports: I had been thinking that I would have to delete everything in /opt/local and start again.
