Accepted Answer

I think you have LIBPATH exported to "/usr/app/oracle/OCI/lib" which has a custom expat library "libexpat.a" which don't have the required shared object member for the Toolbox packages to work. This is the expected behaviour. You have to either unset the LIBPATH system-wide or invoke LIBPATH="" /opt/freeware/bin/dnf
