Ah my faith in Ruby is restored.  Thanks for the make tip Howard;
although it was right in front of me, for some reason I didn't see
this simple solution.  Also thanks for the setup.rb tip Michal, I
think finally I can see a solution to my installation problems.  I
will repackage my stuff using these techniques and post again if there
are any more problems.  Thanks again for the useful help from
everyone.  Cheers,

Rudi
