[mini headsup] updating from 7.x to -CURRENT after lzma import

-----BEGIN PGP SIGNED MESSAGE-----

Hi,

The recent lzma import has enabled libarchive's lzma support.  However,
it have come to our attention that building -HEAD on earlier FreeBSD
versions (specifically, 7.x after 700044 through 8.x before 800022) have
been broken.

The reason behind this is that 'make buildworld' will build a new ar(1)
binary which links to libarchive, causing build to break on these systems.

A hack-ish patch can be used to relieve this:

Alternatively, one can update to 8-STABLE before jumping to 9-CURRENT.

Another way to work around this is to build and install lzma static
library before doing 'make buildworld':

	cd /usr/src
	make buildenv
	cd lib/liblzma
	make obj
	make depend
	make  -DNO_PIC -DWITHOUT_PROFILE -DNO_SHARED all
	make  -DNO_PIC -DWITHOUT_PROFILE -DNO_SHARED install

We are working on a better solution for this and sorry for the breakage.

Cheers,
