[ADMIN] Error during Installation of postgresql-nls-string-8.02.

Hello,

When I try to install postgresql-nls-string-8.02 in postgresql-8.2.5 or in higher version ,it give the following error.

 

ERROR:  incompatible library "/home/local/pgsql/lib/nls_string.so": missing magic block

HINT:  Extension libraries are required to use the PG_MODULE_MAGIC macro.

ERROR:  incompatible library "/home/local/pgsql/lib/nls_string.so": missing magic block

Can anybody tell me what steps I should follow to avoid such type of error during installation of nls_string-8.02 in postgresql-8.2.5 or in higher version ?
