This is not necessarily true if you've got gems (just like perl CPAN
modules) not packaged by cygwin installed.
For that I've hacked a rubyrebase script from the cygwin supplied
perlrebase script. I've attached it here, maybe it can be useful for other
people as well.
Feel free to use it for whatever you want, public domain, CC-0, whatever.
