Exporter Problem

[osler]

I am working with Lingua::StanfordCoreNLP, a module that exports subclasses when used. When I write a script I am able to use Lingua::StanfordCoreNLP and then instantiate objects that are members of the exported subclasses.

Script Code: (straight from the sample code from cpan)

# Note that Lingua::StanfordCoreNLP can't be instantiated.
use Lingua::StanfordCoreNLP;

# Create a new NLP pipeline (silence messages, make corefs bidirection
+al)
my $pipeline = new Lingua::StanfordCoreNLP::Pipeline(1, 1);

# Process text
# (Will output lots of debug info from the Java classes to STDERR.)
my $result = $pipeline->process( $text );

When I try to use Lingua::StanfordCoreNLP in a module that I am writing, I get an error message when I try to instantiate an object member of one of the subclasses. The error message tells me that it can't find the subclass.

My Module Code:

package MyModule;

use Lingua::StanfordCoreNLP;

my $pipeline = new Lingua::StanfordCoreNLP::Pipeline(1, 1);

sub process_text {
  my ($self,$text) = @_;
  $pipeline->process( $text );
}

Can't locate object method "new" via package "Lingua::StanfordCoreNLP::Pipeline" (perhaps you forgot to load "Lingua::StanfordCoreNLP::Pipeline"?)

I think this is a problem related to the difference between run-time and compile-time, but I can't wrap my head around why this isn't working and what I can do differently.
