I downloaded it and installed it with all the recommended options. I
created the LD_LIBRARY_PATH
environment variable but my java compiler (latest version) can't find
packages like org.omegahat.R.java and cannot resolve symbol (class) like
REvaluator, RForeignReference...  any idea ?

many thanks for answering my last question I promise !
best regards,
Anthony
