[1nickt]: See this code. (I expected to simply eval loading threads as a check, but weirdness happened with Perlbrew so it's a grep of -V ...)
[choroba]: Config might be better than grepping -V
[Corion]: Also see Config::V, which is less of that hackery, or that hackery hidden in a module ;)
[1nickt]: The problem was with Perlbrew
[Corion]: Whoops - Config::Perl::V
[1nickt]: I found that when using Perlbrew as recommended, with cpanminus in the system perl lib, such tests were failing to detect the data about the perl that was the install destination.
