Both console-image and nano failed at the same step, trying to 
do_populate_staging on libtool-native. I have now succeeded in getting a 
build of libtool-native, by modifying base.bbclass as follows:

    #
    # old_revision [6f0c90fd27f225177b6d92c123d266df5f5be56e]
    #
    # patch "classes/base.bbclass"
    #  from [1f2aa3e857574c705066c6e22b6697bfafc48da0]
    #    to [652d6fdc46a5e65f33b65bb37a0583e757f6d04e]
    #

The problem was that cd $dir was reporting the new directory to std out, 
causing wc -l to report "2". Likewise, finding the .lai file was 
producing two lines of output.

Why did this affect me, and no one else? Is there anything in my set-up 
that could cause this difference? Which shell should these commands be 
running in? I see that all the scripts in

    build/tmp/work/i686-linux/libtool-native-1.5.10-r10/temp/run.*

specify /bin/sh, so I would have expected the "cd" behaviour to be 
consistent.

Yes, we are specifically interested in the DaVinci.

Thanks,
Douglas.
