load library

Dear friends,

I meet a question in OO perl:

I have a module named:"LDCIDPORTController",
and i define constructor as:

#-------------------------------------
# constructor
# ------------------------------------
sub new
{
  my ($class, $config, $log ) = @_;
  my $self = {};

  $self->{config} = $config;
  $self->{log} = $log;

  bless ( $self, $class);
  return $self;
}


in my main programming, i load this lib by :
#!/tools/perl/bin/perl -I/export/home/yw5726/export/lduser/filter/lib:/export/home/yw5726/export/commonlib

but when i run it, got the error:

Can't locate object method "new" via package "LDCIDPORTController" at /export/home/yw5726/export/commonlib/Manager.pm line 75



Can someone give me some advice how to debug it?

Thanks ahead.
