You have to do it under no strict 'refs', and you make it basically a soft reference (variable resolved from a string). Also you need to watch how $package is in the string. This should work for you. 

my $package_name = 'some_package';
{
   no strict 'refs';
   print Dumper(\%{"main::${package_name}::"});
}
