tar -xzf PLJava-0.04.tar.gz
cd PLJava-0.04
cp Makefile.PL MakeFile.PL
perl Makefile.PL
perl -pi -e "s|CFLAGS=|CFLAGS=-fPIC |" Makefile
make swig

cd built
jar -cf perl5.jar perl5
cp perl5.jar $pwd

My system is 64-bit Fedora 8. I tried JDK 1.6 and JDK 1.5. Both of them gave segmentation fault. Unfortunately, I could not contact the module author anymore. Any suggestion is really appreciated. -jason
