Im running a cron job on cloud sites to collect and process some logs every day (logs are stored on cloud files, cron job is run on cloud sites), but it seems that the fog gem wont load (also using the zlib gem and i assume that isn't loading either). How can I fix this?

Here's an excerpt from the error I recieved:

/usr/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- fog (LoadError)
