Is it even possible?

I have now tried at least 7 different install methods to get pg up and running on Lion. I fear that my system is now
thoroughlyinoculated and will never be able to run postgres/postgis. 

I started with the pg mac installer / stack builder. That worked to get pg installed, but could not get postgis
installed.

I've now tried two different instructions using MacPort, Two using homebrew, and two using
some-other-macport-homebrew-likemethod. 

NONE of them worked for me. I can see postgress running from the last install:

But continue to see this when using psql:
psql: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

Is there anyone who has ever successfully gotten postgres/postGIS running on Mac Lion? Really? How?
Is there a way to purge my system of all of the corrupted/bad installs and start over? How?

How do I get pgadmin if I use homebrew/macports etc?

Would love to believe this is possible, as I cannot stand having to stop whatever I'm doing every 3-4 days to repair
Windows.I hate Windows. I loath Windows, and would love to see the U.S. Economy rebound from all of the production
gainedby everyone universally abandoning Windows…
