My silly patch for showing the package with the problem is:

diff -u -r1.173 bsd.buildlink3.mk
--- mk/buildlink3/bsd.buildlink3.mk	6 Apr 2006 06:23:06 -0000	1.173

 BUILDLINK_PREFIX.${_pkg_}=	BUILDLINK_PREFIX.${_pkg_}_not_found

After using this patch, doing the make  again will have the same errors, 
but will also show the package name with the problem (near my initials).
