No, I am dead serious.

'patch -p1' can't be mentioned on the man pages, because 'patch' is
the utility and '-p1' is the argument to that utility. Invoke 'man patch'
and look for '-p[number]'.

Well, it just happened that your mail reader broke the line starting
with 'fetch -o -' into two. You should invoke the command
{{{
fetch -o - http://people.freebsd.org/~clement/hadoop/hadoop-1.0.0.diff | pa=
tch -p1 -E
}}}
with everything on one line: fetch should feed its output to the patch util=
ity.
By the way, I forgot the -E flag -- it could be needed too.

I think that the Wikipage article about patch is a good thing to start from,
http://en.wikipedia.org/wiki/Patch_%28Unix%29
In a nutshell, since you're doing 'cd /usr/ports', patchfile contents speci=
fy
that diffs are relative to the ports directory,
{{{
--- ports/devel/Makefile 30 Jan 2012 09:15:00 -0000 1.4819
+++ ports/devel/Makefile 1 Feb 2012 16:26:31 -0000
}}}
and -p1 instructs 'patch' utility to strip one directory level
=66rom the file names to be patched, you'll be patching every file
that is mentioned in the diff, but without the leading 'ports/'
prefix, and the base directory will be the $PWD (/usr/ports).
If you really want to understand, what files will be patched, then
here we go:
{{{
$ fetch -qo - http://people.freebsd.org/~clement/hadoop/hadoop-1.0.0.diff |=
grep -E '^(---|\+\+\+) ' | grep -v /dev/null | awk '{print $2;}' | sort | =
uniq | sed -e's,^,/usr/,'
/usr/ports/GIDs
/usr/ports/UIDs
/usr/ports/devel/Makefile
/usr/ports/devel/hadoop/Makefile
/usr/ports/devel/hadoop/distinfo
/usr/ports/devel/hadoop/files/000.java_home.env.in
/usr/ports/devel/hadoop/files/datanode.in
/usr/ports/devel/hadoop/files/hadoop.in
/usr/ports/devel/hadoop/files/jobtracker.in
/usr/ports/devel/hadoop/files/namenode.in
/usr/ports/devel/hadoop/files/patch-build.xml
/usr/ports/devel/hadoop/files/patch-src__c++__libhdfs__hdfs.c
/usr/ports/devel/hadoop/files/patch-src__c++__libhdfs__hdfsJniHelper.c
/usr/ports/devel/hadoop/files/patch-src__native__Makefile.in
/usr/ports/devel/hadoop/files/patch-src__native__configure
/usr/ports/devel/hadoop/files/patch-src__native__configure.ac
/usr/ports/devel/hadoop/files/patch-src__native__src__org__apache__hadoop__=
io__nativeio__NativeIO.c
/usr/ports/devel/hadoop/files/patch-src__native__src__org__apache__hadoop__=
security__JniBasedUnixGroupsNetgroupMapping.c
/usr/ports/devel/hadoop/files/pkg-deinstall.in
/usr/ports/devel/hadoop/files/pkg-install.in
/usr/ports/devel/hadoop/files/secondarynamenode.in
/usr/ports/devel/hadoop/files/tasktracker.in
/usr/ports/devel/hadoop/pkg-descr
/usr/ports/devel/hadoop/pkg-plist
}}}
Again, the command, starting from 'fetch' and ending on 'sed'
must be on a single line.
