Bad command output in MacVim

I'm going throu开发者_Python百科gh the Django tutorial http://docs.djangoproject.com/en/1.2/intro/tutorial01/#activating-models, which outputs colorized SQL snippets via python manage.py sql polls. I'm working with MacVim and it seems that it does not understand the output properly. See screenshot.

This is happening because the terminal emulator supplied by MacVim isn't a fully-functional terminal (i.e. one capable of supporting ANSI escape codes), but it looks like it's claiming to be. You might try this vimscript which claims to be able to colourize files with ANSI escape codes.
