Install pidgin-facebookchat 1.62 in Ubuntu

I tried to install pidgin-facebookchat 1.62 in Ubuntu 9.04. But it gave me an error mentioning that it requires a version of libjson-glib-1.0-0 >= 0.7.6

But you will not be able to install libjson-glib-1.0-0 version >= 0.7.6 using synaptic package manager or apt-get. Therefore, the first thing you have to do is uninstall the old pidgin-facebookchat plugin. Then install libjson-glib-1.0-0 version 0.7.6 from here
