Postgresql Master-Master Replication with Bucardo

I installed Bucardo as below

Current connection settings:

1. Host: 192.168.0.153
2. Port: 5432
3. User: postgres
4. Database: bucardo
5. PID directory: /usr/bin

Enter a number to change it, P to proceed, or Q to quit: P

after proceed -

Postgres version is: 9.4 Attempting to create and populate the bucardo database and schema

INSTALLATION FAILED! (psql:bucardo.schema:46: ERROR: language "plperlu" does not exist HINT: Use CREATE LANGUAGE to load the language into the database.)

The Pl/PerlU language needs to be available This is usually available as a separate package For example, you might try: yum install postgresql-plperl If compiling from source, add the --with-perl option to your ./configure command

I installed postgresql-plperl but when I create plperlu language it giving below error

bucardo=# CREATE LANGUAGE plperlu; ERROR: could not access file "$libdir/plperl": No such file or directory

why this happening any solution ??? appreciate your support

Thanks
