I am a Beginner, help please

["Madhusudan C.S" <madhusudancs gmail com>]

Hi all, 
            I am a beginner to Free Sofware Development, though I am user from past 4 years. I strongly want to contibute to GNOME Community and hence to free Software. So I want some help from you people. 
            I wanted to look at the Source Code of GNOME Games and try fixing small bugs reported in bugzilla. I followed the instruction on this page
http://live.gnome.org/GnomeGames/Contributing
I checked the source from SVN successfully and ran ./autogen.sh for gnome-common with this command ./autogen.sh --prefix=/home/madhu/gnome-builds and then ran make install
I again checked gnome-games and ran  ./autogen.sh --prefix=/home/madhu/gnome-builds but it asks me to install gnome-common again even though I have done it previously. 
     
   Can some one help me please. Thanks for Any Help
