During my recent reinstall of eclipse(long story but all my own fault!) I decided to do a bit of searching around for the "right" way to do it and came accross the following post: http://www.ubuntued.com/?p=40. Just posting it here for both my own future reference and for those of others looking for a step by step method.

Using the above link I've just installed the latest build (3.4) with no problems what so ever. Hope it helps someone else.
