Twitter+OAuth still giving me warnings

Its installed and working but I still get 10 warnings. Is this because the engine is out of date and not 100% compatible with new support libraries? has anyone manage to ge this installed clean with no warnings please share your sources.

I based my installation on "Mark Hammonds on Sep 22nd 2010 " tutorial.

WARNNINGS:

Solved. Turns out the folder needed to be at the root of the project. I Had it in a "external libs" folder.
