I went through several attempts to install a django dev

`sudo port install py25-psycopg2`
which also installed postgresql81 and python25, then I did
'sudo port install postgresql81-server subversion'
after which I should be ready to go, but I am not.
When I run 'python manage.py runserver' in my django project
directory, I get:

Danger, Will Robinson: /usr/local? The python25 port has
inadvertently been linked against the PostgreSQL library found in
your /usr/local directory. This is why we recommend not having
anything in /usr/local. Stuff there frequently conflicts with
MacPorts ports. Please move /usr/local elsewhere, for example /usr/
local-off, then rebuild any ports (such as python25) that have
inadvertently linked against things in /usr/local. Once you're sure
everything works, and once you've replaced anything in /usr/local-off
with ports, remove /usr/local-off.
Using `sudo locate libpq.4.dylib` gives me:
/opt/local/lib/postgresql81/libpq.4.dylib
/opt/local/var/macports/software/postgresql81/8.1.10_0+darwin_8/opt/
local/lib/postgresql81/libpq.4.dylib
I would rather have the system set up to rely on MacPorts so that I
can update/ upgrade with ease. I did install psycopg2 from a dmg
before starting over and installing through MacPorts, so I can only
assume that the system is looking for the old psycopg2 and not
finding the one installed by MacPorts.
I have not created anything yet, and this is only a dev environment
I am trying to set up, so I would be happy to delete a lot of stuff
and start from scratch again, but since I uninstalled everything
and then reinstalled with MacPorts twice, I seem to be missing
someone.
Please advice, and thank you.
