plperl again but different problem

[Marcin Giedz <marcin.giedz@xxxxxxxxxxxxxx>]

Hello..

I've installed plperl.so in postgresql lib directory but when I try to create 
lang, such error occures:

pgsql2-test:~# su pgadmin
pgadmin@pgsql2-test:/root$ /usr/local/postgresql/bin/createlang -p 5433 
plperlu pl
createlang: language installation failed: ERROR:  could not load library 
"/usr/local/postgresql-8.0.3/lib/plperl.so": /usr/local/postgresql-8.0.3/lib/plperl.so: 
undefined symbol: Perl_croak
pgadmin@pgsql2-test:/root$

I've even compiled perl from sources but still have this error. What's going 
on? 

Thx,
Marcin
