[wmii] ENV['WMII_ADDRESS'] problem with latest Ruby-IXP/libixp/wmii?

Me again.

I've now got wmii running on my freshly installed box; next task is to
get ruby-wmii running.

We tried:

svn co svn://svn.gna.org/svn/rubyixp/trunk ruby-ixp
pushd ruby-ixp
rake
sudo rake install
popd

That seems to install the ruby-ixp gem OK. Then:

darcs get http://eigenclass.org/repos/ruby-wmii/branch-ruby-ixp/
pushd branch-ruby-ixp
ruby install.rb
popd

That installs ruby-wmii infrastructure to ~/.wmii-3. Latest wmii
looks for .wmii-3.5 so I set up a soft link:

pushd ~
ln -s .wmii-3 .wmii-3.5
popd

Now running wmii we see in wmiirc.log:

[gimbo_AT_mane ruby-ixp] cat ~/.wmii-3/wmiirc.log

So, it finds the ixp rake OK, but is failing to connect in some way.
Looking at line 129 in client.rb, we see:
    def initialize aSocketPath = ENV['WMII_ADDRESS']
      raise 'Nowhere to connect' unless aSocketPath
So the problem is this ENV['WMII_ADDRESS'].
Any ideas?
