I'm getting this error when trying to use the libmemcache-client-ruby1.8 on Debian Squeeze.
/usr/lib/ruby/1.8/memcache.rb:24:in `read': No such file or directory - /usr/lib/ruby/1.8/../VERSION.yml (Errno::ENOENT)
To troubleshoot, I'm updating ruby1.8. Ugh, now I no longer have irb1.8!!
Oh well, in the end I just edited /usr/lib/ruby/1.8/memcache.rb and changed line 24:
# VERSION = begin
# config = YAML.load(File.read(File.dirname(__FILE__) + '/../VERSION.yml'))
# "#{config[:major]}.#{config[:minor]}.#{config[:patch]}"
# end
VERSION = '1.5.0'
