[Pljava-dev] problems installing PL/Java under Mac OS 10.3.9

I have Postgres v. 8.1.4 and PL/Java 1.3. I build PL/Java from source
(JDK 1.4) and I am
ready to install it in Postgres. I modified the postgresql.conf file
according to the readme
instructions and also installed the latest version JDBC on my system:

dynamic_library_path ='$libdir:/usr/share/pljava/pljava'

custom_variable_classes = 'pljava'

pljava.classpath='/usr/share/pljava/pljava.jar'

Can anybody tell me what the settings for LD_LIBRARY_PATH
should be?

When I execute the PL/Java deployer, I get the following error:

java.sql.SQLExeption: ERROR: could not access file "pljava": No such
file or directory.

Thanks,

Joachim
