Unable to createlang

I am having a problem trying to create a language in a new install of
Postgres
- I have installed postgres 9.1 on a minimal (i.e. no GUI) CentOS 6.2
system.
- Psql is running and I am able to connect to the database from pgAdmin
running on a Windows box.
- Postgres was installed in /opt/postgres
- The data was placed in /var/postgres/data.

I am migrating a database from an 8.4 system to the new system. I am
trying to add the plperl and plperlu languages, which are used in the 8.4
system.

The command I am using is:

createlang -U postgres plperl hf-hvpa

The message I get back is:

createlang: language installation failed: ERROR: could not load
library "/opt/postgres/lib/postgresql/plperl.so": libperl.so: cannot open
shared object file: No such file or directory

I am doing this as the root user, but I have also tried it using my login
and as the postgres user. The plperl.so file is in the indicated directory,
but I am not sure what the reference to libperl.so means. Is that a
separate file I need to download?

I am fairy new to both Linux and Postgres, however I have successfully
installed Postgres on a Windows systems.

Sincerely appreciate any help.

set the LD_LIBRARY_PATH environment variable to the PostgreSQL lib location
location and retry.

Try "ldd /opt/postgres/lib/postgresql/plperl.so" and you'll see what it
means.

PL/Perl needs Perl, and in your case it cannot find the Perl shared
library
in the library search path.

You have several options:
- Rebuild PostgreSQL without --disable-rpath.
- Add the directory that contains libperl.so to /etc/ld.so.conf and
run "ldconfig" as root user. Then start the PostgreSQL server.
- Set the environment variable LD_LIBRARY_PATH to contain the
directory that contains libperl.so and export it in the environment
of the PostgreSQL server. Then start the server.

The third method is the worst.

Another thing:
Never do anything as root user unless you have to. Really.
