To install HTML parser locally (non super user) I would do:

cd ~
mkdir perl_lib
cd HTML-Parser-XXXX
perl Makefile.PL PREFIX=~/perl_lib LIB=~/perl_lib
make && make test && make install
cd ~
setenv PERL5LIB ~/perl_lib
cd HTML-TokeParser-Simple-XXXX
perl Makefile.PL PREFIX=~/perl_lib LIB=~/perl_lib
make && make test && make install

The key part is setting the LIB as the binaries go there. Now in your script you just:

#!/usr/bin/perl
use lib '/home/your_username/perl_lib';
use HTML::TokeParser::Simple;
