I want to connect to an oracle server from my linux 64-bit RHEL machine. I installed the oracle instant client. While installing DBD::Oracle I am getting following message. ( Message comes from the module).

 Unable to locate an oracle.mk, proc.mk or other suitable *.mk file in
+ your Oracle installation.
[download]

I looked basic info and 64-bit info. It doesn't look like a straightforward case. I have "perl: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.4.0, dynamically linked (uses shared libs), not stripped",

Should I use 32-bit Perl? Should I use full oracle client installation? Am I not aware of something? Please guide me appropriately.
Thank you.
