autobuild quits with the following error message because of nil values in
info array.
.gems/gems/autobuild-1.7.10/lib/autobuild/subcommand.rb:101:in `+': nil
can't be coerced into Fixnum (TypeError)

The reason for the the nil values is the result of cpuinfo which is for
ubuntu 14.04 and vmware 6 (full output is attached)

processor : 0
physical id: 0

processor : 1
physical id: 2

processor : 2
physical id: 4
..

One fix would be to compact info or to use a hash instead of an array:
@processor_count = info.compact.inject(&:+)
