The Node hardcopy printout of perl code in your 'update' contains the solution I use for myself: blazar mentioned the LaTeX package 'listings'.

Here is a very basic example:

\documentclass {article}


\usepackage{listings}
\usepackage{color}
\lstset{language=Perl}


\begin {document}

\begin{lstlisting}[frame=trbl]{}
#! /usr/bin/perl

use strict;
use warnings;

print "Intentionally left blank..."; 
\end{lstlisting}

or

\lstinputlisting{your_perl_file_here.pl}

\end {document}
[download]

But check the documentation (pdf): http://tug.ctan.org/tex-archive/macros/latex/contrib/listings/listings-1.3.pdf.
There are many possible configurations: line numbers, highlighting (for perl: print or ignore pod) etc.

It should not be necessary to write a LaTeX generator and I for myself found this solution (although more than a year old) better than so-so :)
