Postgresql installation Errors

Hello
We are currently trying to set up postgresql 7.4.3 on linux Enterprise
Server for use on a software platform called DSpace, as such we have also
installed Java, Apache-Ant and Tomcat 5.0.19 which are required for use with
Dspace. We have been unable to get past the gmake command in the
installation of Pgsql. We have retyped the error we encounter below

[javac]
/usr/dspace/postgresl-7.4.3/src/interfaces/jdbc/org/postgresql/jdbc3/Jdbc3Ca
llableStatement.java:23: error: Invalid checked exception class
'java.sql.SQLExcception' in 'throws' clause. The exception must be a
subclass of an exception thrown by
'org.postgresql.jdbc1.AbstractJdbc1Statment.createRefCursorResultSet(java.la
ng.String)' from calss 'org.postgresql.jdbc1.AbstractJdbcStatement.'

[javac] public PGRefCursorResultSet createRefCursorResultSet
(String cursorName) throws SqlException
[javac]
[javac] 4 errors

We've also noticed that some missing entities such as prototypes,
declarations and arguments during the execution of the gmake command. We
have retyped the error we encounter below

Please note to set up our source tree, we ran configure --enable-multibyte
--enable-unicode --with-java

Your help will be greatly appreciated in setting up pgsql to install
properly.
