I'm using go version go1.5.1 darwin/amd64.

I've tried:

$ GOBIN=. go install
$ echo $?
0
$ ./foo
-bash: ./foo: No such file or directory

And the process exited with status 0 (success), but there was nothing written to current folder.

When I used an absolute path for GOBIN, it worked as expected:

$ GOBIN=`pwd` go install
$ echo $?
0
$ ./foo

From https://tip.golang.org/cmd/go/:

If the GOBIN environment variable is set, commands are installed to the directory it names instead of DIR/bin.

GOBIN - The directory where 'go install' will install a command.

As far as I can tell, nothing in documentation mentions it must be an absolute path. Yet it doesn't work when the path is relative.
