In a mess with libc++ libstdc++ and OSX 10.7.5 Lion

[Ian Wadham]

Hi db and guys,

Good news! I have managed to revert to the previous working versions of all
my ports, in effect reversing the effects of the failed "port upgrade outdated".

Thanks, but I did not try this.  Instead I did something else.

I remembered that, before the "port upgrade outdated" I had uninstalled all
the inactive ports, quite by accident actually --- by not understanding the
full implications of "port -u uninstall xxx", where xxx was a port I no longer
required.  Not only did it uninstall all active and inactive versions of xxx,
but also it went on to uninstall ALL inactive ports…

Anyway, this meant that I could undo the effects of the partial "port upgrade outdated"
simply by:

    sudo port clean akonadi           # Clean the port that failed to upgrade.
    sudo port activate inactive        # Reinstate previous versions of ports that upgraded.

And voila, all is as it was in my Lion machine.  My financial records are accessible again… :-)

In future, I think I will make a list of all active ports before using "port upgrade outdated",
then I can use it to revert the upgrade should anything go wrong.

Thanks very much for all your help,
Cheers, Ian W.
