If you have the META.yml file already created, you could just look for 
a line matching /^version: (\S+)/ in it.  That file is meant to be 
publicly readable, and doing this kind of spot-reading without a full 
YAML parser is very much supported.

If there's a timing issue I'm not considering, i.e. if the META.yml 
file isn't created yet, then we might have to figure something else out.

Also, the new version of Module::Build (0.19) will have a method 
$build->dist_version() that will return the dist_version directly 
instead of doing $build->{properties}{dist_version}.
