Not able to configure Baraha kind of input in 8.4

Hello,

I have followed this link to configure the input

http://dev.sampada.net/Baraha_like_Input_on_Linux

I have installed "scim", "scim-m17n", "scim-gtk2-immodule" and "m17n-db"

Then I created a file 75scim in /etc/X11/Xsession.d/

when i run im-switch -z en_US -s scim-m17n
its giving error as
Error: no configuration file "scim-m17n" exists.
Error: No action taken.

Please help me to configure this properly

Thanks in advance

Arun
