GoInstall: no install location for directory outside GOPATH

[aletheia7]

When I change my GOPATH to a directory other than ~/go, GoInstall fails with with

go install: no install location for directory /opt/someplace/anotherplace/go/src/t outside GOPATH
Press ENTER or type command to continue

Shell: bash
vim-go: 8ac6b9 (today)
GOPATH=~/go

vim-go works great on linux. GOPATH is correct. GoInstall works great. cli "go install" compiles fine with GOPATH=~/go

When I change my GOPATH to another location such as:

export GOPATH=/opt/someplace/anotherplace/go
go env GOPATH
# Output
/opt/someplace/anotherplace/go

and place my app under /opt/someplace/anotherplace/go/src/t, "go install" compiles without errors, however, in vim :GoInstall fails with the error.

No issue with vim-go.
My .vimrc sets the bash shell to use a login shell. It uses:

set shell=/bin/bash\ -l

Therefore, when I would startup vim, the GOPATH would be overridden with the default GOPATH=~/go . This can be diagnosed with launching vim, perform :sh and "go env"
