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:

Gem environment is:

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?
