quite right! thanks Tobias! 

my solution failed to take into consideration the initial directory offset of 
the running process, thus running: "ruby testerequire/file1.rb" would not 
catch the testrequire directory on the first call to require and fail 
subsequently.

so, i have taken your #import solution, using caller[0], and mixed it with 
mine, plus a touch of clean up. let's see if this does the trick:

  alias :require_basic :require
  def require(file_or_directory)
    begin
      fp = File.expand_path(File.dirname(caller[0]))
      $: << fp
      r = require_basic file_or_directory
      i = $:.index(fp)
      $:.delete_at(i) if i
      return r
    rescue
      if FileTest.directory?(file_or_directory)
        require "#{file_or_directory}/#{file_or_directory}"
      else
        raise
      end
    end
  end

notice that, on the recommendation of David, i made the "directory require" 
portion only happen if all else fails. so hopefully this covers all 
contingencies now while being backward compatable (on the whole). even so, i 
bet it can still be cleaned up a bit more. what's your take?
