Yes, your change improved the readability of the messages, thanks.

That said, I'm not sure that this first part is such a problem as it also
happens when building 'beagleboard-demo-image' that does succeed.  Looking
at the results, I see these files:

$ \ls tmp/rootfs/beagleboard-*-image/etc/device_table* -l
-rw-rw-r-- 1 gthomas gthomas 1378 Jun  1 07:37 tmp/rootfs/beagleboard-demo-image/etc/device_table
-rwxr-xr-x 1 gthomas gthomas 6666 May 22 21:17 tmp/rootfs/beagleboard-demo-image/etc/device_table-opkg
-rw-rw-r-- 1 gthomas gthomas 1378 Jun  2 04:35 tmp/rootfs/beagleboard-linuxtag2010-demo-image/etc/device_table
-rwxr-xr-x 1 gthomas gthomas 6666 May 22 21:17 tmp/rootfs/beagleboard-linuxtag2010-demo-image/etc/device_table-opkg

This implies that the same conditions exist for both beagleboard-demo-image
and beagleboard-linuxtag2010-demo-image, so I'm not sure why in one case the
error checker catches it and the other not.

I also don't understand this one as those packages are most
certainly there:

$ tmp/sysroots/i686-linux/usr/bin/opkg-cl -f tmp/rootfs/beagleboard-linuxtag2010-demo-image/etc/opkg/opkg.conf -o tmp/rootfs/beagleboard-linuxtag2010-demo-image list 'encodings*'
encodings - 1:1.0.3-r1.0.5 - Version 1.0.3-r1.0 of package encodings
encodings-dbg - 1:1.0.3-r1.0.5 - Version 1.0.3-r1.0 of package encodings
encodings-dev - 1:1.0.3-r1.0.5 - Version 1.0.3-r1.0 of package encodings

What am I missing?
