[yocto] basic recipe building - iperf

[jfabernathy]

I needed to do some network performance testing on a Crownbay board and 
needed iperf in that environment.  Since I had the core-image-sato-sdk 
image created, I just booted that and took the tarball from Sourceforge 
and built it  per the readme file instructions:

./configure
make
make install

After I completed my test, I thought about why not put that in my list 
of personal recipes.  I found the previous version of iperf in the 
openembedded collection of benchmark recipes and just copied it over.  
It built and worked fine.  There were a lot of items in the .bb that I 
didn't understand, so I thought for fun I'd just try to build a recipe 
for iperf 2.0.5 and see what happened.  My recipe is simple, mostly 
taken from the openembedded 2.0.4 version had stripped down:
-----------------------------
DESCRIPTION = "Iperf is a tool to measure maximum TCP bandwidth, 
allowing the tuning of various parameters and UDP characteristics"
HOMEPAGE = "http://dast.nlanr.net/Projects/Iperf/"
SECTION = "console/network"
LICENSE = "NewBSD"
LIC_FILES_CHKSUM = "file://COPYING;md5=e8478eae9f479e39bc34975193360298"

SRC_URI = " \
     ${SOURCEFORGE_MIRROR}/iperf/iperf-${PV}.tar.gz \
            "
SRC_URI[md5sum] = "44b5536b67719f4250faed632a3cd016"
SRC_URI[sha256sum] = 
"636b4eff0431cea80667ea85a67ce4c68698760a9837e1e9d13096d20362265b"

A lot of it worked, but I seem to have an install error on the man 
files.  Can anyone see what is wrong based on the log below:
