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.
