invoke oracle stored procedure from perl

[perlCrazy]

Hi, I am trying to call Store Procedure (SP) from perl. Getting error.
When I run the SP from sqlplus command: it returns data successfully, like this:
here is the description of procedure:
SQL> describe sp_du
PROCEDURE sp_du
Argument Name Type in/Out Default?
------------ ----------------------- ------ --------
PARA_TB VARCHAR2 IN DEFAULT
PARA_TYPE VARCHAR2 IN DEFAULT
PARA_TEMP_TABLE VARCHAR2 IN DEFAULT
SQL> begin
2 sp_du;
3 end;
4 /
TABLESPACE DATAFILE NAME TOTAL USED USED %
------------ --------------------------------------------- ----- ----- -----
| DBATOOLS /oradata/002/ORAEVLD1/USERTSP/dbatools01.dbf 50 0 2%
| SPOTFIRE_L /oradata/002/ORAEVLD1/USERTSP/SPOTFIRE_LIB_DA 100 1 2%
| SPOTFIRE_L /oradata/002/ORAEVLD1/USERTSP/SPOTFIRE_LIB_IN 50 0 0%
PL/SQL procedure successfully completed.
here is my perl code that I am using to execute

eval {
   my $func = $dbh->prepare(q{
       BEGIN
           :curs := sp_du;
       END;
   });

   # must specify the ora_type of ORA_RSET
   # so code knows it is a cursor
   $func->bind_param_inout(":curs ", \$result,
                   0, { ora_type => ORA_RSET});
   $func->execute;
   $func->finish;
};

if( $@ ) {
   warn "Execution of stored procedure failed use:\n\t$DBI::errstr\n$@
+";
}

while(my $hashRef = $result->fetchrow_hashref)
{
   foreach(keys %$hashRef)
   {
      print "$_ is $hashRef->{$_}\n";
   }
}

$result->finish;

above code throws an error :
Execution of stored procedure failed because: Can't bind unknown placeholder ':curs ' (':curs ') Pls. advice.
Thanks in advance

Try without the space ':curs'
