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.

Thanks
