Can't locate Config.pm in @INC

Applies to: 

Application Install - Version: 11.5.9
This problem can occur on any platform.

Symptoms
When running the following command to generate the context file using note 165195.1
perl adbldxml.pl tier=db appsuser=apps appspasswd=apps
the following error occurs :

ERROR
Can't locate Config.pm in @INC (@INC contains:
/.../perl/lib/5.00503/i686-linux //src/buildarea/asg_apache/pre_shiphome/perl/lib/5.00503

.) at adbldxml.pl line 32.
BEGIN failed--compilation aborted at adbldxml.pl line 32.

Cause
Not able to locate perl therefore not able to execute the perl script.

Solution
To implement the solution, please execute the following steps:

1.Check which perl is being used.

$ which perl
$ perl -version

2. Make sure that the perl is in PATH and the environment file is sourced.
    Before implementing autoconfig, at the step of running adbldxml.pl,
    the applications environment file will not be created,
    therefore you can use the perl delivered by OS.

    The required variables like the PERL5LIB are dynamically created by the script.
