slow pkgsrc installs

[Charles H Dickman <chd_1%nktelco.net@localhost>]

Now that I have a NetBSD/VAX system running again, I see that installing 
from pkgsrc is VERY slow. It seems to spend most of the time running 
configure and testing the same things over and over again. Is there a 
way to make configure cache its findings? Or can pkgsrc be 
cross-compiled as easily as the base system?
