Typo issues

I have been struggling to install typo on my domain
(and have also tried various subdomains). I have followed any availble information found via google, and have found several conflicting install methods, none of which seem to work (i.e. http://convergentarts.com/articles/2005/06/20/typo-on-dh
and http://www.fo64.com/articles/category/how-tos) and typoforums.com

I know people have successfully installed this but I am continually getting errors/dir issues.

If anyone could advise it would be greatly appreciated.
