Greetings all, newbie here. I'm trying to use the latest release of psycopg2 with Python3 and having no success so far.
I'm on Mac OS X Lion (Xcode installed) and I have both 2.7 and 3.2.2 Python installations with 3 set as my default Python
and these are both macports installations.
So if I fire up my 2.7 IDLE session and do: import psycopg2
it appears to work okay, i.e. no errors. (And yes, I am sure it's the 2.7 session)
But the same import in a 3.2.2 IDLE session tells me that no such module exists.
Well, duh, of course, because psycopg2 is probably installed in the 2.7 site package
My two part question is 1) can I use psycopg2 with Python3? (The psycopg2 home site leads me to believe so)
if so 2) How? Here's what I've tried so far:
2a) easy_install would like to install in the 2.7 site install directory, okay, but it's already there, so no thanks
(should I try to force it into the 3.x site installation directory somehow?)
2b) I tried having easy_install load psycopg2 into a separate, empty directory which I put into my PYTHONPATH
variable, just to see what would happen. Didn't work. (See traceback below)
2c) Should I somehow adjust my package search path in 3.2.2 to look in the 2.7 package directory?
What could possibly go wrong with that? ;)
So, should I be doing a, b, c or none of the above? I eagerly await enlightenment and thank you for your time!

(It's been a few years since I've written any Python, so I'm a bit groggy on the package installation
procedures, but it's all slowly coming back)
