You're saying "python package" here, but below, you try to build a C
program.

This should be a folder, not a file. I also recommend to use a relative
path, for example:

	TAMIL_SITE = $(TOPDIR)/../tamil/

Why are you trying to build it as a kernel module ? The program source
code you have below is just a user-space program.

This is just a user-space program. Why do you think you need to use the
"kernel-module" infrastructure ?

Please make sure TAMIL_SITE points to a folder, not a file.
