Tried homebrew - this was a response to another reply Thomas.
brew update
Here I tried:
brew install postgresql
but had this error Error: Failed executing: make install-world
(postgresql.rb:67)
So instead I did this:
brew install postgres --no-ossp-uuid --no-python --no-rubie
Then when running python manage.py runserver I got this error mentioned
first:
Symbol not found: _PQbackendPID
In my virtual env I did not install python, it used my mac installation,
that is correct.
However from the nature of the error it did not look like it relates to
python.
In my settings.py I followed Heroku instructions and put this for the
database:
import dj_database_url
DATABASES = {'default':
dj_database_url.config(default='postgres://localhost')}
Here are some details on my virtual env:
That's the structure, without all the files of course:
venv/lib/python2.7/warnings.pyc venv/include/python2.7/unicodeobject.h
venv/include/python2.7/metagrammar.h
....
venv/lib/python2.7/site-packages:

venv/lib/python2.7/config:

Not sure if these are the details that can help.
