  LOL, this happens so often and with so many languages it deserves an
acronym.

  TCOASSA!

  The missing R is still a clue though.  

---------------------------------------------------<
dk AT rainbow /artimi/tools/linux> ruby --help

   [ ... snip ... ]
  -rlibrary       require the library, before executing your script
---------------------------------------------------<

  So, I dunno if "RUBYOPT=-rrubygems" would work better.  Not without having
rubygems installed, anyway, I don't suppose.  Or perhaps it's one of those
awful puns like "-liberty".

  Hmm.  It suggests here:
http://rubyforge.org/tracker/index.php?func=detail&aid=2497&group_id=126&atid=
576
that it's actually the cygwin package that sets the RUBYOPT variable, even
though it doesn't come with the rubygems library.  If so, that would be a
packaging issue.  OTOH, a quick scan through the package listing for cygwin
ruby doesn't show any postinstall script that could have done that, so I'm not
so sure if the report is accurate: I think you've probably put your finger on
it.


    cheers,
