It's equivalent to moving the furniture to a different room when you do the vacuuming: it enforces a discipline of cleanliness. Simply upgrading every package that you currently installed will result in your computer having dozens of packages installed which you used for one project but don't use anymore. Or worse, you'll have several versions of a package installed with different variants, none of which you actually use anymore (because you used to write in Ruby on Rails, then switched to Django, then switched to Perl with MOOSE, and now you're using WebObjects).

In my experience it doesn't though. Indeed trusting python_select is what got me into trouble. MacPorts’ python_select should, one would think, deal with this. In my experience it doesn’t though.

That would be a concern with easy_install. Does the MacPorts python_select port not take care of those issues? Ah, I see. That would be a concern with easy_install.

This means one only has to be careful about what version of Python is "it" when one creates a virtual environment. After that, you "workon" the virtual environment, and use easy_install to install packages into the virtual environment's path. I do not modify the default or MacPorts installs of Python beyond installing setuptools and virtualenvs. PS: my previous comment about using "port upgrade -force installed" failed on a few packages, so I ended up going with Clark's suggestion of simply removing MacPorts altogether and starting from scratch.

You have to be sure that your Path from .bash_profile is set but that doesn't always happen. Then you have libraries installed by commands like easy_install. If you make sure /opt/bin comes before /usr/bin in your Path <i>at all times</i> and you are careful to just install modules with MacPorts then you should be fine. It's just you have to be very careful otherwise unexpected things can happen. Basically you’re never sure sometimes which version of Python is running.

Hello, this confuses me. I figure that it would be better to install via MacPorts as much as possible, particularly when using the ports prefixed with the version of Python you're using (i.e. py26-scipy). Am I mistaken? I'm new to Python and am eagerly awaiting for certain ports to be fixed in order to get back into it. “Normally I don’t like to install anything Python via MacPorts due to questions of what module is in what install of Python.”

Thanks for the guide. I have a question, have you had any luck getting PIL installed? I have been tearing my hair out and was wondering if anyone else came up with a solution for this.
