For me worked:
    % rm /usr/local/bin/ruby
    % rm /usr/local/bin/irb
    % rm /usr/local/bin/ri
    % rm /usr/local/bin/testrb
    % rm -rf /usr/local/lib/ruby

I wonder where the /usr/local/lib/site_ruby directory comes from.
On my system this is /usr/local/lib/ruby/site_ruby and I've done a
normal ./configure; make; make install of Ruby 1.8.
So perhaps you also want to
    % rm -rf /usr/local/lib/site_ruby
