[PERFORM] Create language plperlu Error

[Om Prakash Jaiswal <op12om@xxxxxxxxxxx>]

Sir/Madam,

Plateform: RHEL6.5,  Postgresql9.4.0.

create extension plperl;

Create language plperl;

I have done following settings:

Perl version 5.10

vi /etc/ld.so.conf.d/libperl.conf

/usr/lib/5.10/multi-thread/i386.../CORE/libperl.so

ldconfig

ERROR: Can not load "/opt/Postgresql/9.4/lib/postgresql/plperl.so" undefined symbol Perl_sv_2bool_flags

ERROR:  could not load library "/opt/PostgreSQL/9.4/lib/postgresql/plperl.so": 
/opt/PostgreSQL/9.2/lib/postgresql/plperl.so: undefined symbol: Perl_sv_2bool_flags

How do I solve.
Kindly resolve it.

Regards
Om Prakash
