Problem installing gems

ruby-talk
1

I cannot install gem files on windows 7 running ruby 1.8.7
I tried to install watir-webdriver -v0.3.3 or selenium-webdriver -v0.2.2
but I got this message:

Building native extensions. This could take a while...
ERROR: Error installing watir-webdriver:
        ERROR: Failed to build gem native extension.

        c:/ruby/bin/ruby.exe extconf.rb

creating extconf.h
creating Makefile

nmake
'nmake' is not recognized as an internal or external command,
operable program or batch file.

Gem files will remain installed in
c:/ruby/lib/ruby/gems/1.8/gems/ffi-1.0.9 for
inspection.
Results logged to
c:/ruby/lib/ruby/gems/1.8/gems/ffi-1.0.9/ext/ffi_c/gem_make.out

any idea how to solve this?

Thanks in advance

nmake is the Micorosoft Visual Studio make tool. Do you have Visual
Studio installed?

A method of solution is perfect if we can forsee from the start,
and even prove, that following that method we shall attain our aim.
