Slackware :: JDK Error (Unknown Source) What To Do

I compiled and installed a new visual traceroute program on my laptop running Slackware 12.1, the program is called GTrace. After an initial ./configure attempt, the program said that I had to install the JDK package. I installed <jdk-6u11-i586-1.tgz> and reconfigured, then make and make install, (I also added a required BerkleyDB <db-2.7.7.tar.gz> file to the install directory, as per the webpage instructions). Now when I try to run the program, it attempts to start ( a window appears onscreen and then just stops and sits there). I then ran the program in the command line and this is the output:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /usr/local/GTrace/libdb/libdb_java.so: /usr/local/GTrace/libdb/libdb_java.so: undefined symbol: __gxx_personality_v0

I searched google for this error and found one user that had a similar output in another program, but after reading the other forum, I have no idea what they were talking about or how to fix this up. How I may overcome this JDK error to be able to run the visual traceroute program.
