mac install question

Please excuse my lack of mac knowledge. I installed postgresql 8.3 using the mac os x 1 click installer onto my brand new powerbook. The install appeared to go very smooth. If I go to Postgresql under Applications it appears as if I can start and stop postgres and open pgadmin. I even created a test database under pgadmin with no errors. So everything appears cool but...

I can't seem to run any of the postgresql commands from a shell. If I open a terminal and try to run psql or createdb or any of the commands I get this error:

/Library/PostgreSQL/8.3/bin/createdb test
dyld: Library not loaded: /Users/buildfarm/pginstaller/server/staging/osx/lib/libpq.5.dylib
Referenced from: /Library/PostgreSQL/8.3/bin/createdb
Reason: image not found
Trace/BPT trap

OR here is me running the psql command

./psql
dyld: Library not loaded: /Users/buildfarm/pginstaller/server/staging/osx/lib/libpq.5.dylib
Referenced from: /Library/PostgreSQL/8.3/bin/./psql
Reason: image not found
Trace/BPT trap

The directory /Users/buildfarm doesn't even appear to exist.

I don't have much experience using mac much less the mac terminal so I assume since everything works from the Applications/PostgreSQL 8.3 Gui that I must just be doing something wrong.

Any help appreciated thanks
