"figure out what other software is putting that version in your environment and stop it from doing so"
I don't think you understand the context here. The Rails dev is saying (correctly) that nobody should be polluting the environment with a variable as vaguely named as "VERSION" this includes Rails.
Rails uses the "VERSION" environment variable temporarily for migrations. They're not trying to "claim" that variable name for themselves only.
