How to include an already written library in a custom library in Arduino

I am creating a new library to control the keyboard and LCD together. Most of the code seems to compile, but when it reaches the line where I define the LiquidCristal variable, it says:

'LiquidCrystal' does not name type when creating user library

This is an excerpt from the contents of my LCDKeypad.h

// Include types & constants of Wiring core API
#if defined(ARDUINO) && ARDUINO >= 100
#include "Arduino.h"
#else
#include "WProgram.h"
#include "WConstants.h"
#endif

// Include LCD library
#include <LiquidCrystal.h>

The error in this line is:

private:
LiquidCrystal lcd( 8, 9, 4, 5, 6, 7 ); // <<-- Error

Well, I read a lot, and I found a very interesting article on this subject:
