rake install from gem_tasks fails

[deivid-rodriguez]

git clone https://github.com/e2/nenv
cd nenv
gem install bundler
bundle exec rake install

gives me

nenv 0.2.0 built to pkg/nenv-0.2.0.gem.
rake aborted!
Couldn't install gem, run `gem install /home/davidr/Work/nenv/pkg/nenv-0.2.0.gem' for more detailed output

(See full trace by running task with --trace)

With 1.10.0.pre2 and earlier it seems to work fine.

Running gem install /home/davidr/Work/nenv/pkg/nenv-0.2.0.gem does work.

This should be fixed by #3707, which will be released shortly.

That's great, thanks!
