Is it something OS specific?

Usually any exec error like this is fairly misleading from the root cause. This is most commonly a missing bash executable. The hashbang in the scripts explicitly use /bin/bash and can probably be replaced with /bin/sh. Give that a try and feel free to submit a PR if that fixes the problem for you. Thanks!
