Title: fix install instructions for ubuntu & other linux

(using Ubuntu version 12.04, but should work for all versions and for many other linux distros)

Two changes:

- suggested using `~/.profile` so it's not short-circuited by the creation of `~/.bash_profile`.
- suggested using `-l` (login shell) option, otherwise the various profile files aren't read.
