Upgrade Django from 1.1 to 1.5.1. This highlights some of the issues that one may encounter when updating Django. It's not possible to cover every case, but this should provide a good general starting point.

Change to DATABASES variable in settings.py.

Django now supports multiple databases and changes are needed to how the database connections are defined.

• Changed in Django 1.2
• Change Required by Django 1.4

Solution: You have conflicting LLVM includes.
rm -rf /usr/local/include/llvm/ /usr/local/include/llvm-c/
Then rebuild graphics/dri

Build Log:
# env MAKE_JOBS_UNSAFE=yes portupgrade --batch -f dri-9.1.7_3,2
[Reading data from pkg(8) ... - 1427 packages found - done]
--->  Reinstalling 'dri-9.1.7_3,2' (graphics/dri)

How to use terminal on Windows without going crazy…

Windows is really horrible system for developers and especially for devops. It doesn’t even have a usable terminal and shell, so working with command line is really pain in the ass. If you really don’t want to switch to any usable system (OS X, Linux, BSD…), then this guide should help you to setup somewhat reasonable environment – usable terminal, proper shell, ssh client, git and Sublime Text as a default editor for shell.

Install stuff

1. Download and install Git for Windows* with:
   • [✘] Use Git from the Windows Command Prompt

• [✘] Checkout as-is, commit Unix-style line endings
