Please help me understand these packages

I've run into this a couple times now and I still don't get it so please help me understand.

I'm trying to understand how to include just the ir-keytable package of the v4l-utils_1.6.2.bb recipe.

At first I was getting a lot of "Nothing PROVIDES" or "Nothing RPROVIDES" error messages when I tried to add it to a package group or as a dependency of another recipe.
However, after I added it directly to IMAGE_INSTALL in my image recipe it mostly seems to be working, no matter where I put it, even after I've removed it from IMAGE_INSTALL in my image recipe. This leads me to believe that maybe I had some sort of database caching problem going on, since I had just back ported the recipe into my branch.

Where it still fails is from the command line:  "bitbake ir-keytable" I don't understand why this fails?

I've had similar problems with the sub-packages of the boost recipe, I can add it boost-program-options to a packagegroup or as a RDEPENDENCY but I can't build it from the command-line.

On the other hand I can build net-snmp-server from the command line, which is a sub-package of net-snmp recipe (interestingly there is no net-snmp package)

I looked at the recipes and they don't seem all that different as far as how the packages are declared.

I'm really confused here can anyone enlighten me.

Thanks,
Matt S.

The reason is that you bitbake <recipe>, not the package name.  The v4l-utils
recipe creates, among other packages, the ir-keytable package.  It works when
you add it to IMAGE_INSTALL because that contains a list of packages, not recipes.
