[LRUG] Rake binstub

[Stephen Best]

Really good point Sam!

I'm not sure what the virtue of removing the `cd` step from your cronjob
is. It sounds way more trouble than it's worth. However this was
interesting to think about the answers were great also.

Gerhard - Not using `bundle exec` in production seems like introducing an
unnecessary discrepancy between environments. I'm sure the core point
you're making is that production servers should have no extraneous packages
installed but I'm just not sure enforcing that by giving up isolation is a
good thing.
