I now have - thanks to the help of many readers of this mailing list -
installed
Ruby 1.8.5 and gem 0.9.3 for both Cygwin and Windows.

Under Cygwin, however, ruby doesn't seem to make use of the installed
gems:


~/tmp $ ruby -rubygem t2.rb
ruby: no such file to load -- ubygem (LoadError)


Under pure Windows, it works fine.

Any idea why this happens? Note that under Cygwin, I use the Ruby
version
which I can load via the Cygwin setup program.
