Please, help me.
I configure/compile perl with option ( other options stay default ):

./Configure -Dprefix=/usr/local/perl -Duseshrplib
make
make install

I add string '/usr/local/perl/lib/5.6.0/i686-linux/CORE'
in file /etc/ld.so.conf and call program 'ldconfig'.

Environment:
LD_LIBRARY_PATH=/usr/local/pgsql/lib:/usr/local/perl/lib/5.6.0/i686-linux/CORE

All is OK for perl. But in psql:

\c db_name

create function perl_hnd() returns opaque as'
/usr/local/perl/lib/5.6.0/i686-linux/CORE/libperl.so' language 'C';

create trusted procedural language 'perl'
handler perl_hnd lancompiler 'perlcompiler';

create function f( int4, int4 ) returns int4 as'
return $_[0] + $_[1]; 'language 'perl';

db_name=> select f(2,2);
ERROR: Can't find function perl_hnd in file
/usr/local/perl/lib/5.6.0/i686-linux/CORE/libperl.so

Please, help me!
