psql: relocation error: psql: undefined symbol: PQgetssl

Hi All,
I just installed postgresql 7.3.4 as an upgrade to 7.3.2 and all went
well untill I tried to log into a database that I successfully created.
  Here are the steps in question:

bash-2.05b$ psql -h localhost -U postgres hardwoodthunder
Welcome to psql 7.3.2, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
        \h for help with SQL commands
        \? for help on internal slash commands
        \g or terminate with semicolon to execute query
        \q to quit

psql: relocation error: psql: undefined symbol: PQgetssl
bash-2.05b$ \q
bash: q: command not found
bash-2.05b$

Does anyone have any suggestions?
thanks,
Phil
