Mercurial 1.9 broken, cannot import readauthforuri

[m@…]

I upgraded to Mercurial 1.9, unfortunately pull and push does not work anymore:

$ hg pull
abort: cannot import name readauthforuri!

Maybe related to py26-mercurial_keyring?

Macports installs mercurial_keyring version 0.4.4, version 0.4.5 contains the following fix:
