Meta: I'd first suggest that you not build your own build system and look at rake instead.

NonMeta: Instead of splitting everything up and nesting your loops, nest your data structure instead:

build = {
  "log" => {
    'where'  =>  'blocks/where.rb',
    'when'   =>  'blocks/when.rb',
    'bank'   =>  'blocks/bank.rb',
  },
  "top" => {
     'where' =>  'blocks/where.rb',
     'when'  =>  'blocks/when.rb',
     'bank'  =>  'blocks/bank.rb',
  }
}

I didn't see any point in having an array of hashes with single pairs in them, so I took that out too.

Absolute paths in build systems are brittle, use relative paths instead.
