Missing file libjava.so for installation

Hi

I have no problem installing Oracle Enterprise Edition 8.1.7.0.1 onto Redhat 9. However when i tried to install Oracle Standard Edition 8.1.7 onto the same server again after removing the previous installation of teh Enterprise Edition, I could not even start my Installer with the missing file libjava.so error. I have unset my LANG and the environment is correct. Any idea what could be wrong or Oracle Standard Edition is not certified to install on Redhat 9? I have no problem starting the Oracle Enterprise Installer in teh same environment but not the Standard edition. Any advices please?
