[HELP] can't get Unixiodbc to connect to SQL

Hi,
I'm new to postgresql Unix iodbc. I am trying to test my unixodbc
connection to a local Postgres DB via the provided "iodbctest" program and
have been unsuccessful in getting a "SQL>" prompt. Instead, it prints out
a "Have nice day" message. Been working on this problem for a week now
and have not come up with anything close at all.
Searched the web and this forum for any "ideas" as to what is wrong and
can't find anything. Any input or help in pointing me to the right
direction is highly appreciated and invaluable.

Thank you in advance for any help on this!

Pasted below is what is currently downloaded and running:
1) Postgres 7.4.3 installed and have created several databases.
