[Libreoffice] Help regarding build from source

Hello there,

I'm a computer science student and want to get into the libre office
development. I went on to IRC # libre office channel for sometime and got
help regarding the git repository cloning and have fetched the source code.

I already have Libreoffice installed on my ubuntu 10.04 system using PPA; so
if I try to buld it libre office from the source which I just fetched will
it affect the existing installation of libre office.
Do I need to remove the pre exesting libre office before I start building
from source ?

Please help me out with this and suggest mehow to move ahead on the path of
contributing to libre office .

Thanks and regards.
