help with jdbc driver building -postgresql sources

Greetings,

I have been trying to install a jdbc driver on Postgres-7.2.1 (source built)
without success.
1. I downloaded the postgres7.21 tarball and decompress it.
2. I downloaded ant-1.41 from http://jakarta.apache.org. I set ANT_HOME
environment variable in bashrc.
3. I downloaded jdk 1.3 from sun and from http://blackdown .org also. I also
set the JAVA_HOME and JAVACMD environment variables in bashrc.
4.I configured postgres with the option --with-java but failed to see a
postgresql.jar file in the final ~/pgsql/share directory.
5.I then decided to try installing the driver: I linked the ant shell-script
to the directory /postgres7.21/src/interfaces/jbdc directory.
6. I executed the ./ant script but on each occasion I get the message
"postgresql-7.2.1/interfaces/jbdc/build.xml:7.2: compile failed, messages
should have been provided".
It seems there are errors in the build.xml file provided in the ~/jdbc
directory and I would be grateful for any help.

Yours sincerely
