Thank you. That was a helpful start. I updated to
RubyGems 1.3.5 and installed the MingGW build with
no apparent problem.

What is "header-file hunting"?
I don't even know where to begin.
Is installing libxml-ruby beyond the scope
of a non-C programmer?

Here is what I get from gem now:

----------------------------------------------------------------------
C:\>gem install -r libxml-ruby
Building native extensions.  This could take a while...
ERROR:  Error installing libxml-ruby:
        ERROR: Failed to build gem native extension.

checking for socket() in -lsocket... no
checking for gethostbyname() in -lnsl... no

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.
----------------------------------------------------------------------

I'm a little confused by "You may need configuration
options." Is that meant for the "gem" command? Or for
the extconf.rb that gem is apparently running?

Any hints on what to do next?

Thanks much.
