how to set environment variables in bash profile
 

I am new to creating packages in Linux we had prepared one software for that, we need to set the environment variables in the roots ./bash_profile in the users machine.
for example i want to add
PATH=$PATH/home/praveen/mydir

is there any way this can be done through the makefile , rpms or in other way.

If I am not able to do this I can't distribute my software.

Actually I am preparing the rpm for this package

Please help me.

Thanks in advance

can't you check for the env's and print out a error if they are not set thus suggesting the user to set those variables?
