$ cat Rakefile
task :default do
  puts ENV['rake']

$ rake
(in /tmp)

It must be following the symlink, or figuring it out somehow.  Here is
the line that blow up in Gem::Ext::RakeBuilder.build:

cmd = ENV['rake'] || "#{Gem.ruby} -rubygems #{Gem.bin_path('rake')}"
rescue Gem.default_exec_format % 'rake'

...it is getting to the rescue clause, because Gem.bin_path('rake')
fails with "can't find gem rake (>= 0)"
