The go get command no longer allows $GOROOT as
the default destination in Go 1.1 when downloading package source.
To use the go get command, a valid $GOPATH is now required.
As a result of the previous change, the go get command will also fail
when $GOPATH and $GOROOT are set to the same value.
More information here: http://golang.org/doc/code.html#GOPATH
