LoadError when using Fog::Compute v0.4.0

[bsedat]

With fog-core 1.45.0 and fog-digitalocean 0.4.0 the following occurs:

>  Fog::Compute.new(:provider => "DigitalOcean", :digitalocean_token => '')
LoadError: cannot load such file -- fog/digitalocean/compute

It looks like the file was removed between v0.3.0 and v0.4.0 but is still being required by fog-core.
