 External projects (hscommon, qtlib, cocoalib) need to be at the root of the dupeGuru project folder.
 You'll have to download those separately. Or use mercurial, it's much easier.
 
-As far as I can tell, you don't *have* to compile/install everything manually and you can normally
-use `easy_install` to install python dependencies. However, be aware that compiling/installing
-manually from the repositories of each project is what I personally do, so if you hit a snag 
-somewhere, you might want to try the manual way.

-PyObjC's website is badly outdated. Also, as far as I can tell, the package installable with
-`easy_install` has good chances of not working. Your best bet is to download the latest tagged
-version from the repository and compile it from source.

 Another one on OS X: I wouldn't use macports/fink/whatever. Whenever I tried using those, I always 
 ended up with problems.
 
-On OSX Lion, for dupeGuru PE, make sure that you installed the latest version of macholib because there was a
-10.7 related bug that was fixed recently. Right now, the fix hasn't even been released yet so you

 You'll probably have to tweak your $PATH.
 
+To setup a build machine under Ubuntu 12.04 and up, install those packages: python3, python3-pyqt4,
+pyqt4-dev-tools, mercurial and then python3-setuptools. Once you've done that, install pip with
+`easy_install`. Once you've done that, you can then perform "The easy way!" installation.
