The provides and rprovides had been set for skipped recipes, packages are similar to them (all of them provide something), so also set it. This makes it easier to figure out the RDEPENDS issues, for example, lmsensors (lmsensors_3.5.0.bb) RRECOMMENDS lmsensors-config-fancontrol (lmsensors-config_1.0.bb), but lmsensors-config is skipped for some reasons, then if we run: $ bitbake lmsensors ERROR: Nothing RPROVIDES 'lmsensors-config-fancontrol' (but /path/to/lmsensors_3.5.0.bb RDEPENDS on or otherwise requires it) NOTE: Runtime target 'lmsensors-config-fancontrol' is unbuildable, removing... Missing or unbuildable dependency chain was: ['lmsensors-config-fancontrol'] ERROR: Required build target 'lmsensors' has no buildable providers. Missing or unbuildable dependency chain was: ['lmsensors', 'lmsensors-config-fancontrol'] We had no way to know who rprovides lmsensors-config-fancontrol, we can figure it out by bitbake/contrib/dump_cache.py after this patch.

Bitbake
BitBake is a generic task execution engine that allows shell and Python tasks to be run efficiently and in parallel while working within complex inter-task dependency constraints. One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software stacks using a task-oriented approach.
For information about Bitbake, see the OpenEmbedded website: http://www.openembedded.org/
Bitbake plain documentation can be found under the doc directory or its integrated html version at the Yocto Project website: http://yoctoproject.org/documentation
Contributing
Please refer to http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded for guidelines on how to submit patches, just note that the latter documentation is intended for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org) but in general main guidelines apply. Once the commit(s) have been created, the way to send the patch is through git-send-email. For example, to send the last commit (HEAD) on current branch, type:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org
