Can I have ActiveGo and another distribution of Go installed together?
The ActiveGo-beta will set GOROOT, GOPATH, and PATH variables. The Golang distribution will also set GOROOT and PATH.
-ActiveGo will always be the default version of Go if both are on the system due to the ways both Go versions set up PATH. Neither ActiveGo nor Golang Go will remove the other distribution from PATH.
-Any value in GOROOT will be overwritten by both versions of Go when they install. The last version to install will be set up as the root. If you remove a version of Go, you will need to re-install/repair the other one to ensure that GOROOT is correct before you start using it.
-GOPATH is your personal workspace. Your workspace should be usable with either version of Go.
