I had been having trouble upgrading to the latest ipython (0.9.1) through macports. In fact, at this point I can’t even access the site, so I’m not sure what’s up. At any rate, the upgrade would fail only because the file ipython-0.9.1.tar.gz couldn’t be downloaded (well, I guess the source file is somewhat important!). So to get it to work I kind of had to brute force it by manually downloading the file (I googled it) and putting it in /opt/local/var/macports/distfiles/python.

Then I ran:

sudo port upgrade py25-ipython

and it went just fine.
