Ran into a few pkg conflicts, 0.4 official:
/usr/bin/bsetroot exists in Blackbox (target) and in Fluxbox (target),
/usr/bin/bsetbg exists in Blackbox (target) and in Fluxbox (target),
/usr/man/man1/bsetroot exists in Blackbox (target) and in Fluxbox (target).
well actually this is a really annoying part of th *boxes. to avoid this you will have to remove the one box in place of the other (ie remove blackbox if you want flux). to make matters even worse i think each of those files is different enough in each *box to not be easily replaceable by the other.fluxbox, blackbox, and openbox all apparently conflict with each other. I compensated, lamely in the openbox package by making fluxbox a conflict and you have just reminded me that i should be adding blackbox to that list.
I am not your friend
NP. I was just going for all or nothing at install; personal preferences regarding wm *box not yet explored. I would eventually decide based on whichever *box gave the most features while not cluttering the desktop.
