JDBC build

I have tried for the entire day to build the JDBC drivers for postgres.
 They will not build.

Here is the error message I keep getting:

/postgresql/postgresql-7.2b1/src/interfaces/jdbc/org/postgresql/Driver.java:210:
';' expected
    [javac]     return ${major};

I cannot figure out what I am missing.

I also cannot find the JDBC jar file anywhere on line.  Maybe I have the
wrong name.

Any and all help will be greatly appreciated.

Thank you,
Denise
