* Rock X has a new version 2.0, which is incompatible with previous

doesn't have an updated version yet which is compatible with X 2.0.
Now rock Y is broken.

	I thought that a move from 1.5 to 2.0 is an upgrade (which can
include incompatibilities) while a move from 1.5 to 1.5.1 is an update
(which should only correct bugs).  LuaRocks could use a more strict
definition of the version number and provide a simple way to update
packages based on the third number.  The Lua team follows this rule,
thus it does not seem to break too much code around.
