Dependencies does not work as expected

[darkstar06]

Hallo,

here is a Example Rakefile which does not work as expected.
At the first run, everything is ok.
Task default, mod1 and mod2 will be executed.
If you rake mod1_clean and rerun rake, mod1 and default will be executed but
mod2 will not be executed.

I would expect mod1 is a pre-requisition of mod2 and mod2 should be rerun if mod1 is updated.

require "biorake/lib/biorake"

event :default => [:mod1, :mod2] do
    puts "execute task default"
end

event :mod1 do 
    puts "execute task mod1" 
end

task  :mod1_clean do 
    rm FileList["./.rake/mod1*"] 
end

event :mod2 do 
    puts "execute task mod2" 
end

Regards darkstar
