はじめに

sudo portmaster security/chkrootkit
===>>> Port directory: /usr/ports/security/chkrootkit

	===>>> This port is marked BROKEN
	===>>> fails to build with new utmpx


	===>>> If you are sure you can build it, remove the
	       BROKEN line in the Makefile and try again.
Terminated

% cd /tmp
% fetch http://people.freebsd.org/~garga/patches/chkrootkit-utmpx.diff
% cd /usr/ports/security/chkrootkit
% sudo patch < /tmp/chkrootkit-utmpx.diff
Hmm...  Looks like a unified diff to me...
The text leading up to this was:
--------------------------
|Index: Makefile
|===================================================================
|RCS file: /home/pcvs/ports/security/chkrootkit/Makefile,v
|retrieving revision 1.32
|diff -u -r1.32 Makefile

--------------------------
Patching file Makefile using Plan A...
Hunk #1 succeeded at 40 (offset -3 lines).
Hmm...  The next patch looks like a unified diff to me...
The text leading up to this was:
--------------------------
|Index: files/extra-patch-utmpx
|===================================================================
|RCS file: files/extra-patch-utmpx
|diff -N files/extra-patch-utmpx
|--- /dev/null  1 Jan 1970 00:00:00 -0000

--------------------------
(Creating file extra-patch-utmpx...)
Patching file extra-patch-utmpx using Plan A...
Hunk #1 succeeded at 1.
done

% sudo mkdir files
% sudo mv extra-patch-utmpx files    
[src]/

ここから普通のビルドになります。

ports コレクションからインストールする場合

*** インストール:

pkgコマンドでインストールする場合。
[src]
