EmonBase and LCD 16x2

Dear all

I would like to connect directly a display (LCD HD44780 16x2)  to Emonbase , in 4bit mode (6 wires) but the "LiquidCrystal"  library conflicts with the  "Jeelib" library. Do I have to use a converter I2C/LCD (http://jeelabs.com/products/lcd-plug) and the  Jeelib library (LCDport)?
Do you know another method?

Thank you in advance.
