Failed to build on Raspberry Pi.

[openedhardware]

Hi, man.

Thanks for your awesome dashboard!

By the way I have been trying to build on my Ubuntu & Raspberry Pi and still have not any luck to succeed.

After installing all dependencies, I just typed ./manage.py db_rebuild and failed.

I had installed postgresql and created role for my current user(default user name of Raspberry Pi is "pi").

But it says:
```
(venv) postgres@raspberry:/home/pi/work/oem_rf/dashboard$ ./manage.py db_rebuild
