merb-more

In merb-cache.rb the DEFAULT_OPTIONS is initialized on class load but Merb.root isn't set at that point.

This causes merb to fail when it can't find the cache directory, and you are using the -m argument, and not starting from the project directory (like via an init script).

A possible fix is to wait to load the defaults until cache start:

def default_config
   @default_config ||= {
    :cache_html_directory => Merb.dir_for(:public) / "cache",
    :store => "file",
    :cache_directory => Merb.root_path("tmp/cache"),
}

Then in the start method:

default_config.merge(Merb::Plugins.config[:merb_cache] || {})
