PHP5.3 on Ubuntu Lucid Lynx 10.4

I found myself needing to install PHP5.3 on a new install of Ubuntu Lucid Lynx 10.4 recently, here's how I did it:

followed:
http://www.robsearles.com/2010/03/17/installing-php5-3-on-ubuntu-karmic/

Had to get libicu38
https://launchpad.net/ubuntu/hardy/amd64/libicu38/3.8-5

Had to remove the newer version of libkrb - which removed apache and everything (couldn't ssh in after this - so need to then
apt-get install openssh-server

wget http://us.archive.ubuntu.com/ubuntu/pool/main/k/krb5/libkrb53_1.6.dfsg.4~beta1-5ubuntu2_amd64.deb

aptitude install libicu38 apache2 apache2-mpm-prefork mysql-client-5.1 mysql-server-5.1 php5 php5-cli php5-mysql libapache2-mod-php5

set timezone in /etc/php5/apache2/php.ini :
date.timezone = Europe/London

I also wanted mod_rewrite:
sudo a2enmod rewrite

aptitude install curl curl-ssl php5-curl

/etc/init.d/apache2 restart

Hope this helps someone.
