I'm having troubling referencing the RegExp::Common $RE variable from inside ParseRecDescent. The following code generates a "ERROR: Internal error in generated parser code!" P.R.D. error. Thanks for the advice --
rkg 
use strict;
use warnings;

package Parser::RKG;

use Parse::RecDescent;
use Data::Dumper;

use RegExp::Common qw(URI);

use constant DEBUG => 0;

$::RD_HINT  = 1 if DEBUG;
$::RD_TRACE = 1 if DEBUG;

my $g = q(

    CommentLine: '#' /.*/
    {{comment=>$item[2]}}

    UriLine: 'u=' /$RE{URI}{HTTP}/ {{uri => $item[2]}}

    Line: CommentLine  | UriLine
    {$item[1]}

  );

sub new {
    my ($class) = @_;
    my $self = {};
    bless ($self, $class);
    $self->{parser} = Parse::RecDescent->new($g);
    $self->{parse_results} = [];
    return $self;
}

sub parse_line {
    my ($self, $line) = @_;
    chomp $line;
    return 1 unless defined($line); # empty is a valid do-nothing
    return 1 unless $line =~ /\S/;  # empty is a valid do-nothing
    print "parsing: $line\n" if DEBUG;
    my $pat = $self->{parser}->Line($line);
    return 0 unless $pat;  # failure
    push ( @{$self->{parse_results}}, $pat );
    return 1;              # success
}

sub parse_results {
    my ($self) = @_;
    return $self->{parse_results};
}

1;
