I broke down and install swig and hacked the paths
for my GSL installation in Makefile and the Python script.
I need the Java source for my IDE.

I just ran TestLog.java and here's the output
JGSL Log computed 2000000 logarithms in 626 ms.
Built-in Log computed 2000000 logarithms in 318 ms.
Java's built in log function appears to be twice as fast as GSL's log
function (on a dual core laptop using Java 6 under Linux.)
