Wire.h not found newliquidcrystal
The liquid crystal library has to be installed in the same folder as the wire library:

libraries/Wire/Wire.h (etc)
libraries/LiquidCrystal/LiquidCrystal_I2C.h (etc)


There is a hard-coded path in the liquid crystal library pointing to the wire library that is relative to where the liquid crystal library is, which is done to get around the problem that the Arduino library doesn't recurse libraries. It's not actually needed since including the Wire library in the IDE is enough to tell it where to find it for the liquid crystal library, so I don't really know why they did it that way.
