Charlie,

You are obviously trying to install Ruby gem that is not ported.

So you can try to imitate a port: install devel/ruby-gems port and do
something like this (in (t)csh):

  # setenv CONFIGURE_ARGS "--with-opt-dir=/usr/local"
  # /usr/bin/env /usr/local/bin/gem install --no-ri \
     --install-dir /usr/local/lib/ruby/gems/1.8 libxml-ruby-0.5.1.0.gem

This will install the gem (try 'gem list'), but you can easily
experience some problems: please note that gem ports (rubygem-*) use
bsd.ruby.mk and devel/ruby-gems/Makefile.common files which contain a
lot of sophistication needed for proper FreeBSD integration.

This is just a very general advice... For details and the right answer,
you could probably ask FreeBSD Ruby person, Akinori Musha
(knu at FreeBSD.org) -- that's what I'd do. :)
