asterisk users - Jan 2007 - newbie asterisk 1.4 installation problem

Hello friends, 
I am trying to install asterisk 1.4. I am configuring it as follows:-
./configure  --prefix=/home/vivek/downloads/install/asterisk/

But still while running 'make install', it tries to install it in 
/var/lib/asterisk/ and stops because of failing permissions. 

I have provided it a prefix, But it doesn't install it there.
Can anybody tell me the solution for this. I dont want to install it in the
default directories. I want it to be in my home directory.




With warm regards.
