Multiple copies of Driver.xst found in: /usr/local/lib64/perl5/auto/DBI/ /usr/lib64/perl5/auto/DBI/ at Makefile.PL line 39.
Using DBI 1.633 (for perl 5.010001 on x86_64-linux-thread-multi) installed in /usr/local/lib64/perl5/auto/DBI/

Configuring DBD::Oracle for perl 5.010001 on linux (x86_64-linux-thread-multi)

Remember to actually *READ* the README file! Especially if you have any problems.

Trying to find an ORACLE_HOME
Your LD_LIBRARY_PATH env var is set to ':/opt/IBM/tivoli/netcool/platform/solaris2/lib:/opt/IBM/tivoli/netcool/omnibus/platform/solaris2/lib:/opt/IBM/tivoli/netcool/platform/solaris2/lib:/opt/IBM/tivoli/netcool/omnibus/platform/solaris2/lib'

      The ORACLE_HOME environment variable is not set and I couldn't guess it.
      It must be set to hold the path to an Oracle installation directory
      on this machine (or a machine with a compatible architecture).
      See the appropriate README file for your OS for more information.
      ABORTED!
