It appears to be very relevant. I followed the instructions in that thread for how to fix forks.pm and not the problem has moved to

Can't locate forks/signals.pm in @INC (you may need to install the for

So, unless I'm misunderstanding something, the forks module needs to be updated to account for the X.Y_Z version numbers or I need to roll Storable back to a X.Y version?
