Yeah, I went down this track as well. And in short, here's where I am:
I didn't have C:\...\PostgreSQL\8.4\bin on my path.
So, after building my env and installing, I added it to my path. "import psycopg2" worked, which was good.
But then, as a sanity check, I nuked the env and am now trying to rebuild it. "pip install psycopg" is currently failing with "Error: pg_config executable not found" even though I've got it on my path and can run it directly from the commandline. Even more odd is how "pip install psycopg2" works *without* PostgreSQL in my path, but *fails* if I have it in. Very, very confusing. :)
Here's the output from "pip install psycopg2" when I have PostgreSQL in my path.

probably dynamically linked to the libpq.dll. I think the system
either fails to find libpq.dll or some of the other dependencies (they
are listed in the setup.py).
I suggest you to use a tool to check its dll dependencies (maybe
http://www.dependencywalker.com/ could be ok) and see if there is
anything missing. If libpq.dll is the missing one, try putting it in a
PATH directory or in the psycopg2 package directory.
Jason, what is the default for building psycopg on windows: static or
dynamic libpq? Is there any default setting we may change to make
psycopg installable with pip/easy_install (if it currently fails - I
don't know).
