I get the following error trying to run the Django development server. I’m using OS X 10.8. I also using virtualenv system install package.

(django-env)Glyns-iMac:Ares Glyn$ sudo python manage.py runserver
dyld: DYLD_ environment variables being ignored because main executable (/usr/bin/sudo) is setuid or setgid

Resolved:

Adding a couple of symbolic links fix this issue for me.

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

sudo ln -s /usr/local/mysql/lib /usr/local/mysql/lib/mysql
