I would have thought any stage one civilisation(I know we are not quite there yet) with the ability to produce antimatter would have met the energy
requirements necessary. Then you also have dark matter/energy to consider, any stage two or three type civilization will almost certainly be able to
manipulate those energy sources which for all intents and purposes are infinite.

Antimatter is extremely difficult to contain, not to mention funnel it through an engine to produce thrust. Although currently we at this time don't
have any method of producing meaningful quantities for space applications, there are some good ideas that get around this issue by using lasers that
are only a few orders of magnitude more powerful than the ones we can produce today. That still doesn't solve the problem of containment/entrapment,
and the potential catastrophe that could ensue if there was a malfunction. Also, antimatter does not fit the "exotic matter" requirement that these
spacetime geometries require.
As for dark matter, it's not something that can be harnessed. If it interacts at all by means other than gravity, then it's most likely through the
weak interaction, which again makes it absolutely impractical for any form of space applications. For dark energy, based on the properties we have
observed of it, it is also going to turn out to be something that cannot be harnessed. If it's indeed a cosmological constant, then attempting to
harness dark energy would be as fruitless as attempting to harness the zero-point field. Although there are
tantalizing new hints
that dark energy may not be a
cosmological constant, unfortunately even a dynamical dark energy is too weak to be useful for any type of technology to make use of. The amount of
dark energy that pervades a cubic meter of space is simply much too small to be detected in the lab, and its effects are really noticeable only on
cosmological (extragalactic) scales.
Edit: Also, both dark and dark energy don't meet the "exotic matter" requirements. The gravitational properties of dark matter is equivalent to that
of baryonic matter, while dark energy is positive energy density with negative pressure. Neither create the "hill" spacetimes that warp drives,
wormholes, and other exotic geometries would require.
