I think your statement rule needs a trailing semi-colon. If you have further problems you should trace the execution. Do this by adding these statements to the program before constructing the parser:
$::RD_TRACE = 1;
$::RD_HINT = 1;
The first one is actually the tracer. Be warned that it will generate a lot of output. Reading it will help you understand what the parser is doing and will probably lead to the error.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
