Ok, after digging deeper I found out:

>          C:/ruby/lib/ruby/site_ruby/resultcache.rb:5: warning: already
>              initialized constant BoundedLruCache

This is due to two conflicting class definitions:

class BoundedLruCache                      # in rockit/bounded_lru_cache.rb
required by rockit
class BoundedLruCache < Hash          # in site_ruby/resultcache.rb required
by Memoize

So how do I overcome this problem ?

Again, any help will be highly appreciated.
TIA,
