Here is the steps for Ubuntu Server 8.04.1 and PHP5. Like Djamu said it will install a GD pre-compiled working version. It is a complete bundled (forked) GD libraries:
1. If not already done removing your current GD package and its configurations. sudo apt-get --purge remove
2. Adding 2 lines to your file /etc/apt/sources.lst
deb http://packages.dotdeb.org stable all </DIV>
deb-src http://packages.dotdeb.org stable all
3. Updating your current apt-get list apt-get update
4. Installing working GD package. apt-get install php5-gd
It will complain about non-authenticated sources, just ignore, it will also update some additional php libs.
When prompt select keep_current modified php.ini
5. Restarting Apache /etc/init.d/apache2 restart
Enjoy
