if it runs perfectly, then u r done 

if it displays some error like: 

system configuration not matching ur evolution configuration, 
then u need to update ur bonobo activation file


UPDATING THE BONOBO-ACTIVATION-CONFIGURATION FILE 

1)Edit ur bonobo-activation-config file 
              $ cd /etc/bonobo-activation 
              $ gedit bonobo-activation-config.xml

check if there is a path which goes like: 
              <!-- <item>/opt/gnome2/lib/bonobo/servers</item> -->


(it might be ur PREFIX instead of /opt/gnome2) 

the important thing is that the line shd be present 


if the line is present then go to step 2) 



if not then add the following line between the <searchpath> and </searchpath> tags 
              <!-- <item>/opt/gnome2/lib/bonobo/servers</item> -->

You will need to restart the bonobo-activation-server process after this (either by logging out and back in or actually killing the process) 


2) If after performing step 1) u still get the above error then, 

add the following line to ur .jhbuildrc file 
            export BONOBO_ACTIVATION_PATH=/PREFIX/lib/bonobo/servers/

(the prefix should be replaced with the prefix ur using. eg: /opt/gnome2 ) 

try loggin out and then back in and try starting evo 

(replace PREFIX with ur prefix)
