What is your problem exactly? What do you mean by "instance"? what is "4.8" ? ...

The path is set from from one of the files .profile, or .bashrc, or .bash_profile (or equivalent for your shell) from your home directory. I believe the sequence the files are run upon login are as above (experts please correct me if I am wrong). If none of these are present in your home, you are inheriting from the system /etc/skel/.*rc or other skel files. Your question is not clear enough though.
