rake sysinfo not reading Cargo.toml dependencies

Perhaps the regex has gone out of date as we've used different ways to specify dependency versions.

IO.read('Cargo.toml').split('[dependencies]').last.split("\n").
    select {|line| line =~ /=/ }.
    each {|line| puts "%s\t%s" % line.match(/(\S+)[ ="']{1,4}([\d.]+)["']?/).captures }
  puts

Output:

I think the Github dependency references have much to do with this.
