1 ### Monkeypatch to work around the broken Rakefile generated by Mkrf <= 0.2.3

     2 

     3 # This fixes:

     4 # * Some weird unnecessary string interpolation

     5 # * The :install task doesn't work unless you have RUBYARCHDIR in your environment, instead of

     6 #   falling back to CONFIG['sitearchdir'].

     7 # * The :install task created the target install directory every time instead of just

     8 #   declaring a dependency on a directory task
