Hi ports --

Looking for mono gurus here. I am trying to port something written in C#
that is supported by mono. According to the port-modules manual page,
MODULES=lang/mono has a variable called MODMONO_NANT, which adds
devel/nant to the BUILD_DEPENDS. Problem is, there is no devel/nant in
the ports tree any more, which pkg_add confirms with "Obsolete package:
nant (outdated and/or no longer required by other ports)."

Attached are some diffs to get rid of those tendrils. Hopefully some of
the mono people can double check this and make sure there aren't other
references to nant.
