Rails - Oct 2010 - Problem with installing linecache on Windows XP

I''ve been trying to move a Rails 2.3.8 app from OXS to Windows XP for
demonstration purposes. I''m having a problem with some of the gems;
linecache is one.
When I try to install the linecache gem, I get the following:
>gem install linecache
Building native extensions.  This could take a while...
ERROR:  Error installing linecache:
        ERROR: Failed to build gem native extension.

C:/Ruby187/bin/ruby.exe extconf.rb

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


Gem files will remain installed in C:/Ruby187/lib/ruby/gems/1.8/gems/
linecache-0
.43 for inspection.

Gem environment is:
>gem environment
RubyGems Environment:
  - RUBYGEMS VERSION: 1.3.7

     - :sources => ["http://rubygems.org/",
"http://gems.github.com"]
  - REMOTE SOURCES:
     - http://rubygems.org/
     - http://gems.github.com

I notice that the platform for the gem is ms-win32, which is
presumably why it fails. This is an issue because I have to prepare
some laptops for a client who wants to develop on windows boxes, so
I''d like to understand what is going on here. I''d also point
out that
the same thing happems with ruby-debug; I haven''t gone through the
whole list of gems that I need yet.

I can force an install with --platform ms-win32 but that seems a
dubious approach to take.

Does anybody have a work-around for this problem?
