Need help on installing Relex on Mac OS X

Hello there,

I have tried to install Relex on Mac OS X 10.5.6. I have followed the instruction and installed all the libraries that required according to the readme. I then used ./configure and ant command on Relex. The result of ant command said "BUILD SUCCESSFUL". I then try to run relation-extractor.sh, but receive this error.

sh-3.2# ./relation-extractor.sh
Info: Using default ./data/wordnet/file_properties.xml
Error: Unable to initialize JWNL:java.lang.NullPointerException
Warning: Unable to initialize WordNet Java API (JWNL).
 Was -Dwordnet.configfile set correctly?
 Does the wordnet.configfile contain the right paths?
 Will use command-line interface; this will negatively impact performance.
Exception in thread "main" java.lang.UnsatisfiedLinkError: no link-grammar-java in java.library.path

What do I miss here? I appreciate your time looking into this

Thank you
