That's exactly what I proposed.  The bsd.port.mk could be patched to
support a new variable ("EARLY_CONFLICT_CHECK=yes" or somesuch) that
shifts the check-conflict target from its old position (part of the
install sequence) to its new position (fetch?).

The default behavior (no mods to /etc/make.conf) would revert to the old
conflict checking method.  This may be something for portmgr@ to chime
in on, and I'm cc'ing them now.  There could be other reasons for this
change that I'm unaware of.
