I've found a conflict between assert2 and ActiveSupport. Both define the method in_groups_of() with different signatures and semantics. It shows up in Ultrasphinx when I run my tests. I've reproduced it in the console, see below. Any suggests on how to force the desired in_groups_of() method?
TIA, Jeffrey
