You could just create a script that outputs the tail information and then does a refresh of itself. If you don't want to use CGI.pm, Try this:

#!/usr/bin/perl

print "Content-type: text/html\n\n";

# Do tail stuff here
my $tail = ...
# Replace carriage returns with br and carriage return
$tail =~ s/\n/<br>\n/g;

# print it out
print <<END_HTML
<html>
<head>
<title>Tail Script</title>
<META HTTP-EQUIV="REFRESH" CONTENT="2; URL=/cgi-bin/cgiscript.cgi">
</head>
<body>
<h1>Tail Program</h1>
<P>
$tail
</body>
END_HTML

Where "cgiscript.cgi" is the name of this script. (You might be able to use $0, but I haven't tried that in a CGI).

Then the browser will refresh to your current CGI every 2 seconds or whatever interval you set in the meta tag.

It's a hack, but it should work.

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
Want more info? How to link or How to display code and escape characters are good places to start.
