[MonetDB-users] Installation Problems

I've been attempting to install MonetDB by compiling the Aug. 2008 superball. My system is 64-bit linux, specifically the Ubuntu Intrepid Ibex alpha . It appears that the installation is failing while compiling the JDBC driver, with the error message:

BUILD FAILED java.lang.UnsupportedClassVersionError: Bad version number in .class file

I'm using the Sun Java 1.5.0 JRE and JDK. You can look at my full installation log here: http://docs.google.com/Doc?id=dhqbmd8x_6fqdnn7c3 Can somebody help me out? I'm hoping I've just made an easily corrected newbie mistake, but I'm out of things to try.

Thanks,

Scott
