Unable to install EM GridControl oms on rhel5 (all 64bit)

Ive experienced problem with installing em gridcontrol oms 64bit on redhat linux 5 64bit. Configuration assistant was unable to start web server with error finding libdb.so.2 library.

We have attemted to install different libs with no success. After few hours of experiments we have decided to use rhel4. It seems that rhel 5 is not supported yet.
