Hi

I am trying to run this perl script

#!/usr/bin/perl

use Bio::Restriction::EnzymeCollection;
my $all_collection = Bio::Restriction::EnzymeCollection;

my $six_cutter_collection = $all_collection->cutters(6);
  foreach my $enz ($six_cutter_collection){
     print $enz->name,"\t",$enz->site,"\t",$enz->overhang_seq,"\n";
     # prints name, recognition site, overhang
  }

but i keep getting the error message "can't use string
"Bio::Restriction::EnzymeCollection;" while strict refs are in use at
../././../EnzymeCollection.pm line 238.

I have no access to change the modules,

please can you help
