def file_search(dirpath, file_regex)
  r = []
  Dir.foreach(dirpath) do |filename|
    next if filename == '.' or filename == '..'
    fullname = "#{dirpath}/#{filename}"
    if FileTest.directory? fullname
      r.concat(file_search(fullname))
    elsif file_regex.match(filename)
      r.push fullname
    end
  end
  r
end

That's quick and dirty, but should give you a starting place to develop what 
you want.  Pass into file_search a starting path (with a trailing '/'), and a 
regex that will match what you are looking for.  You'll get back and array 
with everything that was found to match.
