If you happen to compile with something like
	DESTDIR=/usr/dest//usr2/data/freebsd/src.940225
& that DESTDIR has no X386 tree, it doesnt compile.
If you later say, "yes that compiled clean, Im happy, install in /"
(which does have an X tree)
	setenv DESTDIR /
	make install
it blows up because it never compiled !

Solution:
	compile on one set of if's
	install on a larger set of if's
