Error while installing DBD::Oracle

I am trying to install Perl module DBD::Oracle on my RHEL6.1 server. While doing so, I followed following steps:

Installation of following RPMs:
- oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm
- oracle-instantclient12.1-devel-12.1.0.2.0-1.x86_64.rpm
- oracle-instantclient12.1-sqlplus-12.1.0.2.0-1.x86_64.rpm
Exporting environment variables

export ORACLE_HOME=/usr/lib/oracle/12.1/client64

export LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib
Installing DBD::Oracle

cpan -i DBD::Oracle

While doing so, it gives following error message:

Installing on a linux, Ver#2.6
Using Oracle in /usr/lib/oracle/12.1/client64
DEFINE _SQLPLUS_RELEASE = "1201000200" (CHAR)
Oracle version 12.1.0.2 (12.1)

        Unable to locate an oracle.mk or other suitable *.mk
        file in your Oracle installation.  (I looked in
        /usr/lib/oracle/12.1/client64/rdbms/demo/demo_xe.mk /usr/lib/oracle/12.1/client64/rdbms/lib/oracle.mk /usr/lib/oracle/12.1/client64/rdbms/demo/oracle.mk /usr/lib/oracle/12.1/client64/rdbms/demo/demo_rdbms.mk /usr/lib/oracle/12.1/client64/rdbms/demo/demo_rdbms64.mk /usr/lib/oracle/12.1/client64/rdbms/lib/ins_rdbms.mk /usr/share/oracle/12.1/client64/demo.mk under /usr/lib/oracle/12.1/client64)

        The oracle.mk (or demo_rdbms.mk) file is part of the Oracle
        RDBMS product.  You need to build DBD::Oracle on a
        system which has one of these Oracle components installed.
        (Other *.mk files such as the env_*.mk files will not work.)
        Alternatively you can use Oracle Instant Client.

        In the unlikely event that a suitable *.mk file is installed
        somewhere non-standard you can specify where it is using the -m option:
                perl Makefile.PL -m /path/to/your.mk

        See the appropriate README file for your OS for more information and some alternatives.

     at Makefile.PL line 1187.
Warning: No success on command[/usr/bin/perl Makefile.PL INSTALLDIRS=site]

  /usr/bin/perl Makefile.PL INSTALLDIRS=site -- NOT OK
Running make test
  Make had some problems, won't test
Running make install

What's wrong with the installation process? I followed this guide.

Solution

After the installation and setup of the Oracle Instant Client, use the normal build steps without the cpan tool, and pass the -l option to the Makefile.PL

Download the tar.gz package and unpack it
Build it
```
perl Makefile.PL -l
make && make test
```
Install
```
make install
```
