Subject: ruby-serialport with Ruby 1.9 error

I'm a newbie programmer and I've been trying to communicate with an
Arduino using the ruby-serialport library. If I run this:

require 'rubygems'
require 'serialport'
sp = SerialPort.new "COM3", 9600
sp.write "H"
puts sp.read   # hopefully "OK" ;-)


I get this error (as a windows pop-up box):

'The application has failed to start because msvcrt-ruby18.dll was not
found. Re-installing the application may fix the problem.'


and this ruby error in my command line window:

D:/Ruby19/lib/ruby/gems/1.9.1/gems/ruby-serialport/lib/serialport.rb:1:in
`require': 126:
The specified module could not be found.   -
D:/Ruby19/lib/ruby/1.9.1/i386-mingw32/serialport.so (LoadError)
        from
D:/Ruby19/lib/ruby/gems/1.9.1/gems/ruby-serialport/lib/serialport.rb:1:in
`<top (required)>'
        from ser.rb:2:in `require'
        from ser.rb:2:in `<main>'


As far as I can see, the serialport library was supposed to work with
1.8. There doesn't seem to be a 1.9 version on the GitHub repository
either.

I'm pretty stuck and don't want to learn Python just so I can write
programs for my Arduino (I need to use an email library as well so I can
light an LED each time I get a new email - ie. I can't use
'Processing').

Any suggestions much appreciated.
