You should remember that when you create a custom recipe and you want to add a package to it, you should use the correct name of the package. I mean, Yocto is based on OpenEmbedded and you should use the OpenEmbedded notation and not the Debian notation for the names. Check that you are using the appropriate name for the packages you'd like to add. I suggest you to read section 5.2 of Yocto's Mega Manual (http://www.yoctoproject.org/docs/1.7.2/mega-manual/mega-manual.html).
There is another way to add packages to the image which sometimes is simpler, this is using menuconfig. In case you are interested in this method I suggest you to read section 5.7.1 of Yocto's Mega Manual (http://www.yoctoproject.org/docs/1.7.2/mega-manual/mega-manual.html).
I hope this information is of help.
Thanks Peter,Its helpful
