I guess a good starting place would be the site you pointed to earlier
here it has a source tarball you could download. There's also a set of instructions in the file that should read like
this. I'm afraid I'm not a developer so you'll have to wiat for some other forum members to answer if you have any problems or further questions. I'd search google for details and 'how to' use SVN and building software, this really isn't a place for giving complete tutorials on software building.
