Not sure if Mixins is the right word. But I have require 'rubygems' # # Needed by rbosa, mini_exiftool, appscript, --at least in my installation require 'FileUtils' require 'mini_exiftool' # a wrapper for the Perl ExifTool # I have a couple of others in my script, but these two are the ones conflicting FileUtils and mini_exiftool are apparently both trying to use the same contant. Here's the error I get using TextMate: /usr/local/lib/ruby/1.8/fileutils.rb:93: warning: already initialized constant OPT_TABLE /usr/local/lib/ruby/1.8/fileutils.rb:1163: warning: already initialized constant S_IF_DOOR /usr/local/lib/ruby/1.8/fileutils.rb:1513: warning: already initialized constant METHODS Script runs and is doing what I want AFAIK, but there may be some glitch that I haven't detected yet.
