Subject: Ruby-2.0.0-rc2 on Windows under Cygwin. Cannot run IRB, gem, rake, etc

Hello.

I've successfully (I think so) installed Ruby-2.0.0-rc2 on Windows XP
under Cygwin (1.7.17(0.262/5/3)) using Ruby-builder. It lives now here:

C:\cygwin\usr\local\ruby-2.0.0-rc2 - win path or
/usr/local/ruby-2.0.0-rc2 - cygwin path



It seems it works fine since I can run "ruby -v" and other commands from
the shell like this, for example:

$ ./ruby -e '(1..2).each { |i| puts "This is #{i}" }'
This is 1
This is 2




Please see a pic in the attachment, it is a screenshot of its /bin
directory. The problem is that only ruby.exe works fine. As I said above
I can check it this way and get positive result:

$ ./ruby -e "puts 'Hello World'"
Hello World




But the rest of the files (those unix-like without extensions) just
throw errors:

$ ./gem --help
-bash: ./gem: /usr/local/2.0.0-rc2/bin/ruby: bad interpreter: Permission
denied

$ ./rake --help
-bash: ./rake: /usr/local/2.0.0-rc2/bin/ruby: bad interpreter:
Permission denied


How may I run these Ruby files?

I'm very new to Unix/Linux and yet don't know through and through how it
works. So is the reason I just didn't set some options with Bash or
Cygwin Shell or smth else Unix-specific, or those Ruby commands will
never work under "Windows/Cygwin" environment?
