install libwww-perl
returns with
from ppm (version 3.0.1)
perl -v gives.
"This is perl, v5.8.0 built for MSWin32-x86-multi-thread
(with 1 registered patch, see perl -V for more detail)
Copyright 1987-2002, Larry Wall
Binary build 802 provided by ActiveState Corp. http://www.ActiveState.com
Built 00:54:02 Nov 8 2002"
solution: goto http://www.cpan.org/modules/INSTALL.html and follow instructions to install manually.
AUTHOR: This is technically a mistake, but only because the user is using ppm3 and
not ppm (which is version 2, as indicated in output of that hack).

2nd last paragraph, first word |
h1=en
should read:
hl=en
i.e. the letter "l", not the number "1".
Ditto in the last paragraph, where h1 is also used.

foreach loop in Progress Bar script |
The value of $final_data is not re-initialized upon each iteration of the foreach
loop over the @ARGV array. Consequently, the value of length($final_data) is inflated
for the second and subsequent URLs specified on the command line and the progress
reported is incorrect.
AUTHOR:This is correct. The script and hack was tested with only
one file at a time, even though it supported more than one command line.

2nd code fragment |
In the example code, 2nd fragment, an extraneous character is indicated in the search
string. It currently reads as follows:
my @links = $p->look_down( _tag => 'a', href => qr{^
Ohttp://www.oreilly.com/catalog/E w+ $}x );
and should read:
my @links = $p->look_down( _tag => 'a', href => qr{^
http://www.oreilly.com/catalog/E w+ $}x );

function getBlock (lower half of page) |
the variable $pElement is referenced in the getBlock function, but is never declared
or assigned in this function. This appears to cause the function to fail under some
conditions.
if( $_start > strlen($pElement) && $_stop > $start ) }
should read:
if( $_start < strlen($pSource) && $_stop > $start ) }
