.  I just installed Postgres 7.0.2 on my system and followed the installation instructions to the T.  i even ran the regression tests and everything works fine, until i try to create a database.  logged in as 'postgres', i issue the command "createdb testdb"  i get the following response: 
 
/usr/bin/psql: error in loading shared libraries: /usr/bin/psql: undefined symbol: pg_encoding_to_char
createdb: database creation failed
 
any help with this would be greatly appreciated.  thanks in advance
