Unfortunately, I couldn't ran this on my Project:
gems/rack-mini-profiler-0.1.7/lib/mini_profiler/storage/memory_store.rb:17:in block in initialize': private methodcleanup_cache' called for #Rack::MiniProfiler::MemoryStore:0x00000003bcb670 (NoMethodError)

The line of this error:
https://github.com/SamSaffron/MiniProfiler/blob/master/Ruby/lib/mini_profiler/storage/memory_store.rb#L17

I tried with FileStorage too:
gems/rack-mini-profiler-0.1.7/lib/mini_profiler/storage/file_store.rb:43:in block in initialize': undefined methodinstance' for Rack::MiniProfiler:Class (NoMethodError)

My project is running Rails 3.2.7 with ruby 1.9.3-p194
