If I understand correctly from the above that you have put bblayers.conf in 
conf/ under your meta-bebot layer, that is not correct. bblayers.conf needs to 
be under conf/ in your build directory as usual.

Are you also extending BBFILES and BBPATH in your meta-bebot/conf/layer.conf?

BitBake uses BBFILES to find recipes; each layer's layer.conf typically extends 
BBFILES to find the recipes within the layer. If you are receiving this error 
it means (as you might expect) that BitBake cannot find a provider for the 
specified target. This is either because your bblayers.conf no longer adds the 
path to meta-gumstix to BBLAYERS, or because BBFILES is being reset so that it 
no longer includes the path within meta-gumstix to find the gumstix-console-
image recipe. Please check that you don't have a duplicate bblayers.conf (as 
mentioned above) and that your meta-bebot/conf/layer.conf is appropriately 
extending BBFILES (see other layers for examples).

Cheers,
Paul
