It's interesting. I got the standard build to complete without any 
changes except the SRCREV statements. It booted on the Netbook just 
fine, but without networking.  I went back to the bbappend file and added:

SRC_URI += "file://my_wifi.cfg"

Then created the my_wifi.cfg file to say:

CONFIG_ATH9K_PCI=y

after cleaning sstate and bitbake linux-yocto -c compile -f 
successfully, I couldn't seem to continue.  That when I got the libperl 
error again like I did originally before I added the SRCREV.
