upgrade the guide to use suphp-0.6.3

 replace:

wget http://www.suphp.org/download/suphp-0.6.2.tar.gz
tar xvfz suphp-0.6.2.tar.gz
cd suphp-0.6.2
vi src/apache2/mod_suphp.c

with: 

wget http://www.suphp.org/download/suphp-0.6.3.tar.gz
tar xvfz suphp-0.6.3.tar.gz
cd suphp-0.6.3
vi src/apache2/mod_suphp.c

it works well also with latest version
