RUBYOPT *is* set to -rubygems, so I guess it is a Jruby problem.

As it turns out, I got an email by Jamis Buck (the author of net-ssh),
that
this package would not run with Jruby anyway, so I need to look for a 
completely different solution.

Thank you for helping, though... I wonder whether there is a specific
mailing
list devoted to compatibility issues between Ruby and JRuby. Right now,
I'm
doing a lot of trial and error, to find out what Ruby stuff happens to
work
under JRuby.
