Rouge was just a leaf node in my dependency graph to Jekyll. Now it is
no longer a leaf, it is a node nearly on top... That dependency hell is
frustrating.

I would prefer not skipping the tests. For now I installed Jekyll from
my current distribution (Guix is currently just on top of that). I will
try to find some real leaf nodes later and start with them. But that
has low priority for me.

Thank you for your help,

Björn
