Difficulty installing postgresql on Max OSX Leopard.

[Don Fox-2]

I'm working with an open source Electronic Medical Record  application 'GNUmed" which uses postgresql. I've had a difficult time installing version 8.4.1 from source code on my Mac. 

The best set of instruction i've found is from http://zanshin.net/2009/09/07/installing-postgresql-on-mac-10-6-snow-leopard/,  however it did not quite do the trick. Going by the instructions there:

On starting the server:

 bash-3.2$ /usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data/ -l server.log start  

zanshin.net » Installing PostgreSQL on Mac 10.6 (Snow Leopard) » Blog Archive    server starting

If I use this command to stop server I get: 

/usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsqsl/data/ -l server.log stop

pg_ctl: PID file "/usr/local/pgsqsl/data/postmaster.pid" does not exist

Is server running?

Creating the db:  

    bash-3.2$ createdb testdb

    createdb: could not connect to database postgres: 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"?

 The server.log entries:

       postgres cannot access the server configuration file "/usr/local/pgsql/data/postgresql.conf": No such file or directory

The file does exist

       ls data

      PG_VERSION global pg_hba.conf pg_multixact pg_subtrans pg_twophase postgresql.conf

      base pg_clog pg_ident.conf pg_stat_tmp pg_tblspc pg_xlog postmaster.opts

Also, when attempting to unzip some src files, including the one I got from this site I get this:

tar -zxvf  postgresql-8.4.1.tar.gz

tar: Unrecognized archive format: Inappropriate file type or format

tar: Error exit delayed from previous errors.

THis is very  strange to me!

The file I'm using came from source forge.

Any hints about this installation is greatly appreciated.

P.S. The app that will using postgresql is written in python.
