I solved my own problem, here's how I did it: First I created a new sketch using the Arduino IDE, and saved it where I wanted.
Then I deleted conflicting folders in the libraries Arduino uses, to get there from TextMate, you go: Bundles > Arduino > Open Arduino Libraries
From there you delete conflicting folders, first it complained about Esplora, so into the trash with that. Then RobotController and Motors, and then WiFI.
If anyone has a solution that doesn't require me deleting such libraries, please say so, but for now, this works just fine.
