Error when GOPATH contains multiple entries (master)

[dragonmaus]

When nash is installed from git master (make install), it returns the following error if GOPATH contains multiple path entries:
error[stat /home/dragon/src/go/ext:/home/dragon/src/go/src/github.com/NeowayLabs/nash: no such file or directory] validating nashroot

Changing GOPATH to a single entry prevents the error, but is not a sustainable solution.

What should we do in this case? Use the first gopath directory?

@tiago4orion It should ideally follow go's own behaviour; namely, search all entries of GOPATH when looking for packages, and use the first entry when writing anything.

In this case I think the best thing we can do is avoid look into GOPATH when inferring NASHROOT. Then the behaviour will be: look if NASHROOT variable is set, if not use $HOME/nashroot.
